Protein attributes

Sequence length	229 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Inactivates PAF by removing the acetyl group at the sn-2 position. This is a catalytic subunit.
Catalytic activity	1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + H2O = 1-alkyl-sn-glycero-3-phosphocholine + acetate.
Subunit structure	Cytosolic PAF-AH IB is formed of three subunits of 45 kDa (alpha), 30 kDa (beta) and 29 kDa (gamma). The catalytic activity of the enzyme resides in the beta and gamma subunits, whereas the alpha subunit has regulatory activity. Trimer formation is not essential for the catalytic activity.
Subcellular location	Cytoplasm.
Developmental stage	Expressed already by the time of neurulation. By E10.5, expression is abundant in the developing central and peripheral nervous systems. Major sites include the neuroepithelium of the fore-, mid-, and hindbrain, the spinal cord, the dorsal root, and cranial ganglia.
Sequence similarities	Belongs to the 'GDSL' lipolytic enzyme family. Platelet-activating factor acetylhydrolase IB beta/gamma subunits subfamily.
