PAFAH1B2

Platelet-activating factor acetylhydrolase (PAFAH) inactivates platelet-activating factor (PAF) into acetate and LYSO-PAF. This gene encodes the beta subunit of PAFAH, the other subunits are alpha and gamma. Multiple alternatively spliced transcript variants have been described for this gene.

Interaction

Forms a catalytic dimer which is either homodimer (alpha2/alpha2 homodimer) or heterodimer with PAFAH1B3 (alpha2/alpha1 heterodimer). Component of the cytosolic (PAF-AH (I)) heterotetrameric enzyme, which is composed of PAFAH1B1 (beta), PAFAH1B2 (alpha2) and PAFAH1B3 (alpha1) subunits. The catalytic activity of the enzyme resides in the alpha1 (PAFAH1B3) and alpha2 (PAFAH1B2) subunits, whereas the beta subunit (PAFAH1B1) has regulatory activity. Trimer formation is not essential for the catalytic activity (By similarity). Interacts (homodimer form) with PAFAH1B1 (homodimer form); PAFAH1B2 competes with NDEL1 for PAFAH1B1 binding (PubMed:15572112). Interacts with VLDLR; this interaction may modulate the Reelin pathway (By similarity).
