Biotype
protein coding gene
Automated Description
Enables protein kinase C binding activity and small GTPase binding activity. Involved in several processes, including establishment of mitotic spindle localization; gonad development; and polarity specification of anterior/posterior axis. Located in P granule and cell cortex. Is extrinsic component of cytoplasmic side of plasma membrane. Is expressed in several structures, including AB; EMS; P0; Psub1; and excretory cell. Orthologous to several human genes including PARD6B (par-6 family cell polarity regulator beta).
WB Description
par-6 encodes a PDZ-domain-containing protein that is conserved in Drosophila and mammals; during development, maternally provided PAR-6 is required for establishing anterior-posterior polarity in the early C. elegans embryo; par-6 activity is also essential for determining proper apicobasal asymmetries associated with cell adhesion and gastrulation; PAR-6 localizes to the periphery of the newly fertilized embryo, and then becomes more prominent in the anterior periphery as well as the advancing cleavage furrow during the first mitosis; in germline precursors, PAR-6 localizes asymmetrically to sites that correspond to the future EMS and C blastomeres; in somatic cells, by the end of the four-cell stage, PAR-6 is seen as a 'cap' centered on the apical surface; in embryos, PAR-6 colocalizes with PAR-3 and is mutually dependent upon PAR-3 and PKC-3 for proper localization, suggesting that these proteins may act in a complex to establish embryonic polarity; PAR-6 localization is also dependent upon wild-type activity of par-4.
