CC -!- FUNCTION: Regulatory subunit (beta subunit) of the cytosolic type I
CC platelet-activating factor (PAF) acetylhydrolase (PAF-AH (I)), an
CC enzyme that catalyzes the hydrolyze of the acetyl group at the sn-2
CC position of PAF and its analogs and participates in PAF inactivation.
CC Regulates the PAF-AH (I) activity in a catalytic dimer composition-
CC dependent manner (By similarity). Positively regulates the activity of
CC the minus-end directed microtubule motor protein dynein. May enhance
CC dynein-mediated microtubule sliding by targeting dynein to the
CC microtubule plus end. Required for several dynein- and microtubule-
CC dependent processes such as the maintenance of Golgi integrity, the
CC peripheral transport of microtubule fragments and the coupling of the
CC nucleus and centrosome. Required during brain development for the
CC proliferation of neuronal precursors and the migration of newly formed
CC neurons from the ventricular/subventricular zone toward the cortical
CC plate. Neuronal migration involves a process called nucleokinesis,
CC whereby migrating cells extend an anterior process into which the
CC nucleus subsequently translocates. During nucleokinesis dynein at the
CC nuclear surface may translocate the nucleus towards the centrosome by
CC exerting force on centrosomal microtubules. Also required for proper
CC activation of Rho GTPases and actin polymerization at the leading edge
CC of locomoting cerebellar neurons and postmigratory hippocampal neurons
CC in response to calcium influx triggered via NMDA receptors. May also
CC play a role in other forms of cell locomotion including the migration
CC of fibroblasts during wound healing. Required for dynein recruitment to
CC microtubule plus ends and BICD2-bound cargos. May modulate the Reelin
CC pathway through interaction of the PAF-AH (I) catalytic dimer with
CC VLDLR (By similarity). {ECO:0000250|UniProtKB:P43033,
CC ECO:0000250|UniProtKB:P43034, ECO:0000250|UniProtKB:P63005,
CC ECO:0000255|HAMAP-Rule:MF_03141}.
CC -!- SUBUNIT: Can self-associate. Component of the cytosolic PAF-AH (I)
CC heterotetrameric enzyme, which is composed of PAFAH1B1 (beta), PAFAH1B2
CC (alpha2) and PAFAH1B3 (alpha1) subunits. The catalytic activity of the
CC enzyme resides in the alpha1 (PAFAH1B3) and alpha2 (PAFAH1B2) subunits,
CC whereas the beta subunit (PAFAH1B1) has regulatory activity. Trimer
CC formation is not essential for the catalytic activity. Interacts with
CC the catalytic dimer of PAF-AH (I) heterotetrameric enzyme: interacts
CC with PAFAH1B2 homodimer (alpha2/alpha2 homodimer), PAFAH1B3 homodimer
CC (alpha1/alpha1 homodimer) and PAFAH1B2-PAFAH1B3 heterodimer
CC (alpha2/alpha1 heterodimer) (By similarity). Interacts with DCX,
CC dynein, dynactin, IQGAP1, KATNB1, NDE1, NDEL1, NUDC and RSN. Interacts
CC with DISC1, and this interaction is enhanced by NDEL1. Interacts with
CC DAB1 when DAB1 is phosphorylated in response to RELN/reelin signaling.
CC Interacts with INTS13. Interacts with DCDC1.

CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton {ECO:0000255|HAMAP-
CC Rule:MF_03141}. Cytoplasm, cytoskeleton, microtubule organizing center,
CC centrosome {ECO:0000255|HAMAP-Rule:MF_03141}. Cytoplasm, cytoskeleton,
CC spindle {ECO:0000255|HAMAP-Rule:MF_03141}. Nucleus membrane
CC {ECO:0000255|HAMAP-Rule:MF_03141}. Note=Localizes to the plus end of
CC microtubules and to the centrosome. May localize to the nuclear
CC membrane. Redistributes to axons during neuronal development. Also
CC localizes to the microtubules of the manchette in elongating spermatids
CC and to the meiotic spindle in spermatocytes. {ECO:0000255|HAMAP-
CC Rule:MF_03141}.
CC -!- DOMAIN: Dimerization mediated by the LisH domain may be required to
CC activate dynein. {ECO:0000255|HAMAP-Rule:MF_03141}.
CC -!- MISCELLANEOUS: Originally the subunits of the type I platelet-
CC activating factor (PAF) acetylhydrolase was named alpha (PAFAH1B1),
CC beta (PAFAH1B2) and gamma (PAFAH1B3) (By similarity). Now these
CC subunits have been renamed beta (PAFAH1B1), alpha2 (PAFAH1B2) and
CC alpha1 (PAFAH1B3) respectively (By similarity).
