InnateDB Gene

IDBG-146219 (Pfn2)

Protein Structure

UniProt Annotation

Function

Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. By binding to PIP2, it inhibits the formation of IP3 and DG.

Subcellular Localization

Cytoplasm, cytoskeleton.

Disease Associations

Tissue Specificity

Isoform IIa is the main isoform and is abundant in brain. Isoform IIb is a minor isoform.
