cyclin B1

General Information (Source: NCBI Gene,UniProt)

Text mining Term	cyclin B1
UniProt ID	KALRN_RAT
Name	Serine/threonine-protein kinase with Dbl- and pleckstrin homology domain P-CIP10 Kalirin Huntingtin-associated protein-interacting protein PAM COOH-terminal interactor protein 10 Protein Duo
Gene Names	Kalrn
Taxonomy	Rattus norvegicus

General annotation

Function	Promotes the exchange of GDP by GTP. Activates specific Rho GTPase family members, thereby inducing various signaling mechanisms that regulate neuronal shape, growth, and plasticity, through their effects on the actin cytoskeleton. Induces lamellipodia independent of its GEF activity. Isoforms 1 and 7 are necessary for neuronal development and axonal outgrowth. Isoform 6 is required for dendritic spine formation.
Subcellular location	Cytoplasm. Cytoplasm, cytoskeleton. Note=Isoform 6 is largely associated with synaptosomal membranes and to punctate structures in cortical neurons. Isoforms 1 and 7 are expressed in neuronal cell bodies, isoform 7 is also found in neuronal processes.
