Involved in several processes, including establishment of T cell polarity; negative regulation of activated T cell proliferation; and synaptic vesicle cycle. Acts upstream of or within several processes, including nervous system development; post-anal tail morphogenesis; and wound healing. Located in several cellular components, including basolateral plasma membrane; immunological synapse; and myelin sheath abaxonal region. Is expressed in several structures, including alimentary system; embryo mesenchyme; genitourinary system; hair follicle; and nervous system. Orthologous to human SCRIB (scribble planar cell polarity protein). [provided by Alliance of Genome Resources, Apr 2022]
