. "FUNCTION: Necessary for signaling by class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance, neuronal growth cone collapse and cell migration (By similarity). SUBUNIT: Homotetramer, and heterotetramer with CRMP1, DPYSL2, DPYSL4 or DPYSL5 (By similarity). Interacts with synaptic vesicle protein 2 and SH3A domain of intersectin (By similarity). SUBCELLULAR LOCATION: Cytoplasm (By similarity). Cell projection, growth cone (By similarity). Note=Colocalizes with synaptic vesicle protein 2 in the central region of the growth cone (By similarity). ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q14195-1; Sequence=Displayed; Name=LCRMP-4; IsoId=Q14195-2; Sequence=VSP_042546; TISSUE SPECIFICITY: Mainly expressed in heart and skeletal muscle. Also strongly expressed in fetal brain and spinal cord. PTM: Phosphorylation on Ser-522 by DYRK2 promotes subsequent phosphorylation on Thr-509, Thr-514 and Ser-518 by GSK3. SIMILARITY: Belongs to the DHOase family. Hydantoinase/dihydropyrimidinase subfamily. CAUTION: Lacks most of the conserved residues that are essential for binding the metal cofactor and hence for dihydropyrimidinase activity. Its enzyme activity is therefore unsure.
