Rabbit anti-Human PIK3C3 Polyclonal Antibody

Uniprot Id

Q8NEB9

Target Species

Human

Target Name

PIK3C3

Target Full Name

Phosphatidylinositol 3-kinase catalytic subunit type 3

Target Function

Catalytic subunit of the PI3K complex that mediates formation of phosphatidylinositol 3-phosphate; different complex forms are believed to play a role in multiple membrane trafficking pathways: PI3KC3-C1 is involved in initiation of autophagosomes and PI3KC3-C2 in maturation of autophagosomes and endocytosis. As part of PI3KC3-C1, promotes endoplasmic reticulum membrane curvature formation prior to vesicle budding. Involved in regulation of degradative endocytic trafficking and required for the abcission step in cytokinesis, probably in the context of PI3KC3-C2. Involved in the transport of lysosomal enzyme precursors to lysosomes. Required for transport from early to late endosomes.

Target Subcellular Location

Midbody. Late endosome. Cytoplasmic vesicle, autophagosome.

Target Protein Families

PI3/PI4-kinase family

Target Tissue Specificity

Ubiquitously expressed, with a highest expression in skeletal muscle.

Target Background

Enables 1-phosphatidylinositol-3-kinase activity. Involved in early endosome to late endosome transport and regulation of cytokinesis. Acts upstream of or within autophagy and protein lipidation. Located in autolysosome; late endosome; and midbody.
