Genes affected

SYT9 (HGNC:19265): (synaptotagmin 9) Predicted to enable several functions, including calcium ion binding activity; phospholipid binding activity; and syntaxin binding activity. Predicted to be involved in calcium-ion regulated exocytosis; cellular response to calcium ion; and regulation of secretion by cell. Predicted to be located in clathrin-coated endocytic vesicle membrane. Predicted to be active in hippocampal mossy fiber to CA3 synapse; plasma membrane; and secretory vesicle. Predicted to be integral component of synaptic vesicle membrane. [provided by Alliance of Genome Resources, Apr 2022]
