Status

Functioni

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. Also 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. May also play a role in other forms of cell locomotion including the migration of fibroblasts during wound healing (By similarity). Non-catalytic subunit of an acetylhydrolase complex which inactivates platelet-activating factor (PAF) by removing the acetyl group at the SN-2 position. Required for pronuclear migration during fertilization.UniRule annotation1 Publication

Interactioni

Subunit structurei

Can self-associate. Interacts with DCX, IQGAP1, KATNB1, NDEL1, NUDC and RSN. Interacts with DISC1, and this interaction is enhanced by NDEL1. Interacts with DAB1 when DAB1 is phosphorylated in response to RELN/reelin signaling (By similarity). Interacts with dynein, dynactin and NDE1. 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 ASUN (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
