Overview
GAP43 This protein is associated with nerve growth. It is a major component of the motile growth cones that form the tips of elongating axons. Plays a role in axonal and dendritic filopodia induction. Identified in a complex containing FGFR4, NCAM1, CDH2, PLCG1, FRS2, SRC, SHC1, GAP43 and CTTN. Binds calmodulin with a greater affinity in the absence of Ca(2+) than in its presence. Belongs to the neuromodulin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
