motifs/domains

N-terminal domain, including its myristoylation site, the central alpha-helix, and the C-terminal lobe containing EF-hands 3 and 4 of HPCAL4 are sufficient to transfer its regulatory properties to Calmodulon

SUBCELLULAR LOCALIZATION

basic FUNCTION	may be involved in the calcium-dependent regulation of rhodopsin phosphorylation
	is a calmodulin -related Ca2+-binding protein, and a neuronal calcium sensor protein

INTERACTION

DNA

RNA

small molecule	metal binding,
	Ca2+ binding

protein	differential regulation of CACNA1A channels by Calmodulin, HPCAL4, CABP1, and other neurospecific Ca2+-binding proteins is a potentially important determinant of Ca2+ entry in neurotransmission
	NRF1 could be a regulatory factor for VSNL1 gene expression and for other visinin-like subfamily members including HPCAL4, HPCAL1, HPCA, and NCALD
	inhibits inactivation and enhances facilitation of CACNA1A channels
