Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000639
UniProt IDQ9BQT9
Primary gene name(s)CLSTN3
Synonym gene name(s)CS3, KIAA0726
Protein nameCalsyntenin-3
Protein functionMay modulate calcium-mediated postsynaptic signals. Complex formation with APBA2 and APP, stabilizes APP metabolism and enhances APBA2-mediated suppression of beta-APP40 secretion, due to the retardation of intracellular APP maturation. {ECO:0000250}.
Subcellular locationCell membrane {ECO:0000305};
Single-pass type I membrane protein {ECO:0000305}. Endoplasmic reticulum membrane. Golgi apparatus membrane. Note=Most prominent in the postsynaptic specializations of asymmetric, type I synapses with both axodendritic and axospinous localization. {ECO:0000250}.
