B-cell receptor-associated protein 29
BAP29 and the related protein BAP31 are endoplasmic reticulum (ER) and ER-vesicle membrane proteins and members of the B-cell receptor-associated protein family. These two proteins are highly homologous and can form homo- and heterodimers. Both BAP29 and BAP31 interact with membrane-bound immunoglobulins (mIgs), such as IgM and IgD, which with Ig-alpha/Ig-beta heterodimers form B cell antigen receptors. Binding of the BAP29/BAP31 heterodimer correlates with the ER retention of non-Ig-alpha/Ig-beta bound mIg complexes, suggesting that BAP29 and BAP31 may act as chaperones for transmembrane regions of various proteins. There are multiple isoforms of BAP29.
