Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance. During the axon guidance process, acts downstream of SEMA3A to promote FLNA dissociation from F-actin which results in the rearrangement of the actin cytoskeleton and the collapse of the growth cone. Involved in invasive growth and cell migration. May participate in cytokinesis. CRMP1 Protein, Human, Recombinant is expressed in E. coli expression system. The predicted molecular weight is 62.2 kDa and the accession number is Q14194.
