The function of Ensembl gene identifier ENSG00000072832 (CRMP1, collapsin response mediator protein 1) is as follows. Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton (PubMed:25358863). Plays a role in axon guidance (PubMed:25358863). 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 (PubMed:25358863). Involved in invasive growth and cell migration (PubMed:11562390). May participate in cytokinesis (PubMed:19799413). {ECO:0000269|PubMed:11562390, ECO:0000269|PubMed:19799413, ECO:0000269|PubMed:25358863}.
