PI 3 Kinase Class 3 rabbit pAb

Catalytic activity: ATP + 1-phosphatidyl-1D-myo-inositol = ADP + 1-phosphatidyl-1D-myo-inositol 3-phosphate. Cofactor: Manganese. function: Catalytic subunit of the PI3K complex. Involved in the transport of lysosomal enzyme precursors to lysosomes. similarity: Belongs to the PI3/PI4-kinase family. similarity: Contains 1 PI3K/PI4K domain. subunit: Probably forms a complex with AMBRA1 and BECN1 (By similarity). Heterodimer. This subunit, part of a complex composed of regulatory and catalytic subunits, associates with regulatory subunit PIK3R4. tissue specificity: Ubiquitously expressed, with a highest expression in skeletal muscle.
