Rabbit anti Human BAP31 antibody recognizes the human chaperone protein, B-cell receptor-associated protein 31, also known as BAP31. BAP31 is a 246 amino acid ~28 kDa conserved multi pass type III integral transmembrane protein of the endoplasmic reticulum, containing two caspase cleavage sites within its cytosolic domain.

BAP31 appears to be a multi-functional ER-associated transport protein which was originally identified through its association with membrane IgD in B-cells (Adachi et al. 1996). Several proteins have since been shown to associate with BAP31, including the Beta2 integrin receptor CD11b/CD18 (Zen et al. 2004), non-muscle gamma-actin and myosin B heavy chain (Ducret et al. 2003). BAP31 has become a focus area for apoptosis studies due to its association with Bcl-2 and cleavage by initiator caspases including caspase 1 and 8 generating a membrane-integrated p20 fragment which is itself a potent inducer of apoptosis when expressed ectopically (Breckenridge et al. 2003).

Rabbit anti Human BAP31 antibody detects BAP31 as a band of approximately 24 kDa in a wide range of human cell line lysates.
