PAFAH1B1
From Wikipedia the free encyclopedia
Platelet-activating factor acetylhydrolase IB subunit alpha or Lisencephaly protein-1 (LIS-1) is an enzyme that in humans is encoded by the PAFAH1B1 gene.[5][6][7] The protein plays an important role in regulating the motor protein dynein.[8]
Function
[edit]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 VLDL receptor activated by reelin.[9]
Genomics
[edit]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
[edit]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]
