The antibody detects endogenous levels of total APIP protein.

The mammalian homologues of the key cell death gene CED-4 in C. elegans has been identified recently from human and mouse and designated Apaf 1 (for apoptosis protease-activating factor 1) (1,2). Apaf 1 binds to cytochrome c (Apaf 2) and Caspase-9 (Apaf 3), which leads to Caspase-9 activation. Activated Caspase-9 in turn cleaves and activates Caspase-3 that is one of the key proteases, being responsible for the proteolytic cleavage of many key proteins in apoptosis (3). Recently, Cho et al (4) have identified a new Apaf 1 Interactiong Protein (APIP) also known as CG129 and MMRP19, as a negative regulator of ischemic injury. APIP competes with Caspase-9 binding site of Apaf 1. APIP is predicted to code for a 204 amino acid. An isoform of APIP, APIP2 encodes a 242 amino acid protein, which is an alternative splicing variant differing in its N-terminus from APIP. APIP transcript is ubiquitously expressed in most adult tissue with high expression in skeletal muscle, heart, and kidney.
