PIK3R4 ELISA kits are immunoassay tools for the measurement of the protein phosphoinositide-3-kinase regulatory subunit 4, which is encoded by the PIK3R4 gene in humans. Functionally, this protein is a regulatory 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. The canonical protein structure is reported to have an amino acid length of 1358 residues, a mass of 153.1 kDa, and is a member of the Ser/Thr protein kinase protein family. It is known to be localized in the cytoplasmic vesicles and is ubiquitously expressed across many tissue types. The protein has been noted to be post-translationally myristoylated and phosphorylated. Other alias names for this target include p150, PI3-kinase p150 subunit, PI3-kinase regulatory subunit 4, phosphatidylinositol 3-kinase-associated p150, and VPS15.
There are PIK3R4 ELISA kits that can detect a target at concentrations as low as 0.156 ng/mL and as high as 10 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
