NSF Cellular Processes Cluster (PD 11 1114) - FAQs

What is the NSF Cellular Processes Cluster funding opportunity?

The NSF Cellular Processes Cluster (PD 11 1114) is a discretionary research grant program within the National Science Foundation (NSF) Biological Sciences directorate under CFDA 47.074. It supports fundamental, curiosity-driven research in cell biology focused on advancing foundational understanding of how cells are built, organized, and operate.

What kinds of research does this program aim to support?

The program is designed to push the field forward by encouraging genuinely innovative approaches and enabling projects that address long-standing, foundational questions in cell biology. It favors work that is integrative and connects phenomena across scales, especially bridging supramolecular assemblies (large, multi-component molecular structures) and whole-cell behaviors.

Is this program focused on basic science or applied outcomes?

This opportunity emphasizes fundamental cell biology and mechanism-driven discovery. Proposals are expected to prioritize basic understanding of cellular mechanisms rather than primarily targeting applied or translational outcomes.

What does NSF mean by "integrative work that connects phenomena across scales"?

Based on the program description, NSF is interested in proposals that link molecular or supramolecular organization (for example, macromolecular assemblies) to larger-scale cellular structure, dynamics, and behavior. The emphasis is on connecting nanoscale organization to microscale and whole-cell outcomes rather than studying isolated components without broader integration.

How important are rigor and quantification in this program?

Rigor and quantification are central themes. NSF signals interest in proposals that go beyond descriptive observations by measuring, modeling, and testing mechanisms with quantitative precision. Competitive proposals are likely to include quantitative experimentation, data analysis, theoretical frameworks, and/or mechanistic modeling.

Does NSF encourage multidisciplinary or cross-disciplinary approaches?

Yes. The program welcomes multidisciplinary teams and cross-cutting approaches that incorporate tools and perspectives from physics, mathematics, engineering, and computational science, especially when these methods support quantitative and mechanistic insight into cellular organization and dynamics.

What technical or conceptual areas are highlighted as being of particular interest?

The cluster highlights several areas, including live-cell imaging, single-particle analysis of macromolecular assemblies, and studies of the architectural organization and dynamics of cellular structures across broad dimensional scales. Collectively, these areas reflect an interest in capturing dynamics, heterogeneity, and spatial organization.

What is live-cell imaging in the context of this program?

In this opportunity, live-cell imaging refers to approaches that observe cellular structures and processes in real time under physiologically relevant conditions. The emphasis suggests value in studying dynamic cellular behavior rather than relying only on static snapshots.

What is meant by "single-particle analysis of macromolecular assemblies"?

This refers to work that tracks or characterizes individual molecular complexes (or particles) to understand how large macromolecular structures assemble and function. The description frames this broadly as a way to study assembly and function at the level of individual complexes.

What does "architectural organization and dynamics across broad dimensional scales" mean?

It means studying how cellular structures are organized and change over time while explicitly linking different size scales, such as connecting nanoscale organization (molecular or supramolecular) to microscale structures or whole-cell architecture and behavior.

What scientific topics are within the scope of this cluster?

The program entertains proposals across major areas of cell biology, including (1) membrane organization and function, (2) organelle biogenesis, maintenance, and trafficking, and (3) cytoskeletal dynamics, cell division, and motility. Proposals are expected to aim for mechanistic clarity and conceptual advances, especially when connecting molecular mechanisms to cell-level outcomes.

What types of questions fit under membrane organization and function?

Within the scope described, membrane organization and function can include how membranes create compartments, regulate transport, organize signaling, and maintain physical properties that influence cellular behavior.

What types of questions fit under organelle biogenesis, maintenance, and trafficking?

Within the scope described, this area covers how organelles are formed, how they maintain identity and function over time, and how materials and membranes are moved within cells.

What types of questions fit under cytoskeletal dynamics, cell division, and motility?

Within the scope described, this includes the machinery that provides cellular structure, drives intracellular transport, enables chromosome segregation, and allows cells to move and change shape.

Are biomedical or disease-focused proposals appropriate for this opportunity?

No, not if the research is motivated primarily by human disease relevance or health outcomes. NSF explicitly notes (with reference to its Grant Proposal Guide) that proposals whose main driver is human disease or health are considered inappropriate for this division and may be returned without review.

Can a proposal mention potential biomedical implications?

Yes, but only as secondary context. The opportunity description indicates that the primary justification must be fundamental cell biology and understanding basic cellular mechanisms; downstream biomedical implications should not be the central driver.

How many awards and how much total funding were anticipated?

At the time of posting, NSF expected approximately 70 awards with an estimated total funding level of about $14,000,000.

Is cost sharing or matching required?

No. The opportunity states there is no cost sharing or matching requirement.

Who is eligible to apply?

Eligibility is listed as unrestricted, meaning the program is broadly open to applicant organizations, subject to any additional eligibility clarifications in the full program text.

What is the CFDA number and why does it matter?

The opportunity is listed under CFDA 47.074 within NSF Biological Sciences. The CFDA identifier is used to categorize federal assistance programs and may help applicants and institutions track the appropriate program area.

What is the referenced solicitation number for applications?

Applications were directed to NSF 11-545, as referenced in the opportunity information.

What were the proposal deadlines listed for this opportunity?

The listed proposal deadlines were January 12, 2011; July 12, 2011; and a "current closing date" of September 6, 2011.

What time period was this opportunity active?

The posting dates indicate the opportunity was active around 2010-2011, with deadlines in 2011 and a closing date listed as September 6, 2011.

What type of activity category does NSF list for this grant?

The opportunity is issued by NSF under the "Science and Technology and other Research and Development" activity category.

Where should applicants go for submission or technical support related to Grants.gov?

For practical submission or access issues, NSF points applicants to Grants.gov support via grantsgovsupport@nsf.gov.

What proposal characteristics are implied to be competitive?

Based on the description, competitive proposals are likely to be innovative, integrative across scales, and strongly quantitative, combining advanced experimental strategies with theory, data analytics, and/or mechanistic modeling to produce deeper and more generalizable insight into cellular organization and dynamics.
