PAFAH1B1 Antibody – Rabbit Polyclonal

Function: Required for proper activation of Rho GTPases and actin polymerization at the leading edge of locomoting cerebellar neurons and postmigratory hippocampal neurons in response to calcium influx triggered via NMDA receptors. Non-catalytic subunit of an acetylhydrolase complex which inactivates platelet-activating factor (PAF) by removing the acetyl group at the SN-2 position (By similarity). Positively regulates the activity of the minus-end directed microtubule motor protein dynein. May enhance dynein-mediated microtubule sliding by targeting dynein to the microtubule plus end. Required for several dynein-and microtubule-dependent processes such as the maintenance of Golgi integrity, the peripheral transport of microtubule fragments and the coupling of the nucleus and centrosome. Required during brain development for the proliferation of neuronal precursors and the migration of newly formed neurons from the ventricular/subventricular zone toward the cortical plate. Neuronal migration involves a process called nucleokinesis, whereby migrating cells extend an anterior process into which the nucleus subsequently translocates. During nucleokinesis dynein at the nuclear surface may translocate the nucleus towards the centrosome by exerting force on centrosomal microtubules. May also play a role in other forms of cell locomotion including the migration of fibroblasts during wound healing. Required for dynein recruitment to microtubule plus ends and BICD2-bound cargos (PubMed:22956769).
Subunit Structure: Component of cytosolic PAF-AH IB, which is composed of PAFAH1B1 (alpha), PAFAH1B2 (beta) and PAFAH1B3 (gamma) subunits. Trimer formation is not essential for the catalytic activity of the enzyme which is contributed solely by the PAFAH1B2 (beta) and PAFAH1B3 (gamma) subunits. Interacts with IQGAP1, KATNB1 and NUDC. Interacts with DAB1 when DAB1 is phosphorylated in response to RELN/reelin signaling (By similarity). Can self-associate. Interacts with DCX, dynein, dynactin, NDE1, NDEL1 and RSN. Interacts with DISC1, and this interaction is enhanced by NDEL1. Interacts with ASUN. Interacts with DCDC5 (PubMed:22159412).
Similarity: Dimerization mediated by the LisH domain may be required to activate dynein. Belongs to the WD repeat LIS1/nudF family.

Small volumes of anti-PAFAH1B1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
