Formalin-fixed and paraffin-embedded human breast carcinoma tissue reacted with PI3KC2B antibody (N-term), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining.
Protein kinases are enzymes that transfer a phosphate group from a phosphate donor, generally the g phosphate of ATP, onto an acceptor amino acid in a substrate protein. By this basic mechanism, protein kinases mediate most of the signal transduction in eukaryotic cells, regulating cellular metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. With more than 500 gene products, the protein kinase family is one of the largest families of proteins in eukaryotes. The family has been classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains.1) Arcaro, A., et al., J. Biol.

Immunogen
This PI3KC2B antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 120-150 amino acids from the N-terminal region of human PI3KC2B.
