About Pik3c3

Chromosome 18: 30,405,800-30,481,179 forward strand.GRCm39:CM001011.3

This gene has 4 transcripts (splice variants), 210 orthologues, 9 paralogues and is associated with 19 phenotypes. Broad expression in CNS E14 (RPKM 15.), CNS E18 (RPKM 11.) and 24 other tissues.

Summary

Enables protein kinase activity. Involved in cellular response to glucose starvation and macroautophagy. Acts upstream of or within several processes, including cellular response to starvation; phosphatidylinositol-3-phosphate biosynthetic process; and protein localization to phagophore assembly site. Located in phagocytic vesicle. Part of phosphatidylinositol 3-kinase complex, class III. Is expressed in Meckel's cartilage; cardiovascular system; limb; and skeleton. Orthologous to human PIK3C3 (phosphatidylinositol 3-kinase catalytic subunit type 3). [provided by Alliance of Genome Resources, Apr 2022]
