RT   "Phactr4 regulates directional migration of enteric neural crest through
RT   PP1, integrin signaling, and cofilin activity.";
RL   Genes Dev. 26:69-81(2012).
CC   -!- FUNCTION: Regulator of protein phosphatase 1 (PP1) required for neural
CC       tube and optic fissure closure, and enteric neural crest cell (ENCCs)
CC       migration during development. Acts as an activator of PP1 by
CC       interacting with PPP1CA and preventing phosphorylation of PPP1CA at
CC       'Thr-320'. During neural tube closure, localizes to the ventral neural
CC       tube and activates PP1, leading to down-regulate cell proliferation
CC       within cranial neural tissue and the neural retina. Also acts as a
CC       regulator of migration of enteric neural crest cells (ENCCs) by
CC       activating PP1, leading to dephosphorylation and subsequent activation
CC       of cofilin (COF1 or COF2) and repression of the integrin signaling
CC       through the RHO/ROCK pathway. {ECO:0000269|PubMed:17609112,
CC       ECO:0000269|PubMed:22215812}.
CC   -!- SUBUNIT: Binds PPP1CA and actin.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm. Cell projection, lamellipodium.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative splicing; Named isoforms=3;

CC       Name=3;
CC         IsoId=Q501J7-3; Sequence=VSP_025439;
CC   -!- DEVELOPMENTAL STAGE: During embryonic development, most strongly
CC       expressed in neural tissue. Expressed in a dynamic pattern during
CC       neurulation: from 8.5 dpc to 9.5 dpc, the period of cranial neural
CC       closure and spatially regulated proliferation, it is expressed strongly
CC       in the ventral region of the cranial neural tube. By 10.5 dpc,
CC       expressed more uniformly along the dorsal and ventral aspects of the
CC       cranial neural tube. Also expressed in the neural retina and lens.
CC       {ECO:0000269|PubMed:17609112}.
CC   -!- DISRUPTION PHENOTYPE: Neural tube and eye defects in embryos followed
CC       by death. By 9.25 dpc, mutant embryos show failure to close the cranial
CC       neural tube. About 15% of homozygous mutant embryos exhibit severe
CC       exencephaly, along with a wavy spinal neural tube and a shortened
CC       anterior/posterior body axis, and die around 10.5 dpc. Remaining
CC       embryos exhibit complete exencephaly from the forebrain to hindbrain.
CC       Most embryos die by 14.5 dpc, but a few survive to birth and die
CC       shortly thereafter. Embryos also have eye defects: they display
CC       overgrowth of the neural retina and retinal pigment epithelium. Embryos
CC       also display coloboma at 12.5 dpc and 16.5 dpc, due to defects in
CC       closure of optic fissure. Defects are due to elevated proliferation and
CC       abnormally phosphorylated, inactive PP1, resulting in RB1
CC       hyperphosphorylation, derepression of E2F targets, and abnormal cell-
CC       cycle progression. Embryos also show embryonic gastrointestinal defects
CC       due to colon hypoganglionosis, which resembles human Hirschsprung
CC       disease: ENCCs within the embryonic gut display a collective cell
CC       migration defect and show undirected cellular protrusions and disrupted
CC       directional and chain migration. {ECO:0000269|PubMed:17609112,
CC       ECO:0000269|PubMed:22215812}.
CC   -!- SIMILARITY: Belongs to the phosphatase and actin regulator family.
