Background Information
CAP1, also known as CAP, CAP1-PEN, belongs to the CAP family and contains 1 C-CAP/cofactor C-like domain. CAP1 binds to monomeric actin and regulates the actin cytoskeleton to control cell size, adhesion, and migration (PMID: 23737525). CAP1 also functions as a receptor for inflammatory cytokine resistin (PMID: 24606903). CAP1 is an abundant and ubiquitously expressed protein. Western blot analysis detected CAP1 at an apparent molecular mass of 50-55 kDa.
