Comments [?]

case <OC:Mammalia>
Function 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. Non-catalytic subunit of an acetylhydrolase complex which inactivates platelet-activating factor (PAF) by removing the acetyl group at the SN-2 position.

May be required for proliferation of neuronal precursors and neuronal migration.
else case <OC:Saccharomycotina> or <OC:Cryptococcaceae>
Function Positively regulates the activity of the minus-end directed microtubule motor protein dynein. Plays a central role in positioning the mitotic spindle at the bud neck during cell division. Targets cytoplasmic dynein to microtubule plus ends, thereby promoting dynein-mediated microtubule sliding along the bud cortex and consequently the movement of the mitotic spindle to the bud neck.

Function 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 nuclear migration during vegetative growth as well as development. Required for retrograde early endosome (EE) transport from the hyphal tip. Required for localization of dynein to the mitotic spindle poles. Recruits additional proteins to the dynein complex at SPBs.

case <OC:Mammalia>
Subunit Can self-associate. Interacts with DCX, dynein, dynactin, IQGAP1, KATNB1, NDE1, 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. 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.
else case <OC:Vertebrata>
Subunit Can self-associate. Interacts with dynein, dynactin, @gn(NDE1) and @gn(NDEL1).
else case <OC:Eurotiales>
Subunit Self-associates. Interacts with nudE and dynein.
else case <OC:Fungi> and not <OC:Eurotiales>
Subunit Self-associates. Interacts with @gn(NDL1) and dynein.
else case <OC:Nematoda>
Subunit May be a component of a dynein regulatory complex composed of at least lis-1 and nud-2. Interacts with nud-2.

Subcellular location Cytoplasm, cytoskeleton. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytoskeleton, spindle. Nucleus membrane. Note=Localizes to the plus end of microtubules and to the centrosome. May localize to the nuclear membrane. Redistributes to axons during neuronal development. Also localizes to the microtubules of the manchette in elongating spermatids and to the meiotic spindle in spermatocytes.
