Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables GTP-dependent protein binding activity and small GTPase binding activity. Involved in cell-cell junction maintenance and positive regulation of protein secretion. Acts upstream of or within negative regulation of protein phosphorylation. Located in several cellular components, including apical part of cell; bicellular tight junction; and cell cortex. Is expressed in several structures, including 2-cell stage conceptus; brain; genitourinary system; gut; and lung. Orthologous to human PARD6A (par-6 family cell polarity regulator alpha).
