The P101-PI3K ELISA kits listed below are analytical tools for measuring concentrations of P101-PI3K in various samples. P101-PI3K is an alternative name for the human PIK3R5 gene, which encodes the protein, phosphoinositide-3-kinase regulatory subunit 5. It has been mentioned that P101-PI3K plays a role in GPCR signaling pathways and immune response pathways, among other functions. Structurally, the PIK3R5 protein is 880 amino acid residues in length and 97.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane, nucleus, and cytoplasm of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. Other names for this target antigen include F730038I15Rik, FOAP-2, and P101-PI3K. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
