Platelet-activating factor acetylhydrolase IB subunit alpha is an enzyme that in humans is encoded by the PAFAH1B1 gene.[5][6][7] The protein is often referred to as Lis1 and plays an important role in regulating the motor protein Dynein.[8]

Function

PAFAH1B1 was identified as encoding a gene that when mutated or lost caused the lissencephaly associated with Miller–Dieker syndrome. PAFAH1B1 encodes the non-catalytic alpha subunit of the intracellular Ib isoform of platelet-activating factor acetylhydrolase, a heterotrimeric enzyme that specifically catalyzes the removal of the acetyl group at the SN-2 position of platelet-activating factor (identified as 1-O-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine). Two other isoforms of intracellular platelet-activating factor acetylhydrolase exist: one composed of multiple subunits, the other, a single subunit. In addition, a single-subunit isoform of this enzyme is found in serum.[7]

According to one study, PAFAH1B1 interacts with VLDLR receptor activated by reelin.[9]

Genomics

The gene is located at chromosome 17p13.3 on the Watson (plus) strand. The gene is 91,953 bases in length and encodes a protein of 410 amino acids (predicted molecular weight 46.638 kiloDaltons).

Interactions

PAFAH1B1 has been shown to interact with DYNC1H1,[10] CLIP1,[11] NDEL1,[12][13] NDE1,[14] PAFAH1B3,[15] PAFAH1B2,[15] NUDC,[16] TUBA1A[17] and Doublecortin.[18]
