RN [4] RP PROTEIN SEQUENCE OF 61-79 AND 134-142, AND MASS SPECTROMETRY. RC TISSUE=Hippocampus; RA Lubec G., Klug S.; RL Submitted (MAR-2007) to UniProtKB. CC -!- FUNCTION: Inactivates PAF by removing the acetyl group at the sn-2 CC position. This is a catalytic subunit. CC -!- CATALYTIC ACTIVITY: 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + CC H(2)O = 1-alkyl-sn-glycero-3-phosphocholine + acetate. CC -!- SUBUNIT: Cytosolic PAF-AH IB is formed of three subunits of 45 kDa CC (alpha), 30 kDa (beta) and 29 kDa (gamma). The catalytic activity CC of the enzyme resides in the beta and gamma subunits, whereas the CC alpha subunit has regulatory activity. Trimer formation is not CC essential for the catalytic activity. CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- DEVELOPMENTAL STAGE: Expressed already by the time of neurulation. CC By E10.5, expression is abundant in the developing central and CC peripheral nervous systems. Major sites include the CC neuroepithelium of the fore-, mid-, and hindbrain, the spinal CC cord, the dorsal root, and cranial ganglia. CC -!- SIMILARITY: Belongs to the platelet-activating factor CC acetylhydrolase IB beta/gamma subunits family.
