Protein
Plasma membrane-associated cation-binding protein 2
Organism
Arabidopsis thaliana
Function
May be involved in intracellular signaling through interaction with PtdInsPs and calmodulin (CaM); may keep PtdInsPs attached to the plasma membrane until Ca(2+)-CaM reaches a competitive concentration subsequent to an increase triggered by a stimulus, thus leading to PtdInsPs release and subsequent activation of InsPs-dependent signaling cascade (Probable). Binds to microtubules and inhibits tubulin polymerization. Regulates directional cell growth and cortical microtubule organization by destabilizing microtubules (e.g. in cotyledon pavement cells) (PubMed:17337629).
Similarity
Belongs to the DREPP family.
