What it is Filled
Caveolins are a family of small, oligomer-forming integral membrane proteins that participate in caveola formation and membrane lipid organization, with distinct family members differing in tissue distribution and function.
In scope
- Caveolin family membership, organism, paralog, isoform and sequence identity
- Native and engineered caveolin proteoforms, modifications and preparation quality
- Membrane association, oligomer composition and assembly state
- Cellular abundance, localization, trafficking and turnover
- Context-dependent interactions, functional evidence and responses to perturbation
Out of scope
- CAV gene loci and transcriptional regulation as independently modeled genetic entities
- Caveolae as complete membrane structures with their own morphology and dynamics
- Cavin proteins, other membrane scaffolds and lipid constituents as independent entities
- Whole-cell signaling networks and endocytic pathways beyond demonstrated caveolin contributions
- Disease diagnosis, patient management and therapeutic products
- Commercial antibodies, expression vectors and assay kits as products
Why it exists Filled
Enable an agent to identify caveolin proteins, assess their molecular and cellular state, and select justified measurements or perturbations of their membrane-associated functions.
Distinguishing features Filled
- Require sequence-supported caveolin family membership; caveolar localization alone does not establish protein identity.
- Resolve caveolin-1, caveolin-2 and caveolin-3 separately when applicable, recording organism and isoform instead of treating a family-level label as an exact molecular identity.
- Distinguish caveolin proteins from cavin coat proteins through sequence identity and family annotation, even when both occur in the same membrane structure.
- Distinguish a caveolin molecule or oligomer from a caveola: detecting the protein does not establish a complete membrane invagination.
- Use membrane topology and assembly evidence as supporting identifiers; the human caveolin-1 8S structure is a member-specific reference, not a universal structure for every caveolin. Reference: [RCSB PDB 7SC0](https://www.rcsb.org/structure/7SC0).
What robots and AI may and may not do Filled
