Automated description from the Alliance of Genome Resources
Exhibits GTP binding activity; GTPase activity; and myosin V binding activity. Involved in several processes, including leukocyte degranulation; melanocyte differentiation; and melanosome transport. Localizes to the Golgi apparatus; cytoplasmic vesicle; and photoreceptor outer segment. Used to study Hermansky-Pudlak syndrome 1; hemophagocytic lymphohistiocytosis; and platelet storage pool deficiency. Human ortholog(s) of this gene implicated in Griscelli syndrome type 2 and non-Langerhans-cell histiocytosis. Is expressed in 4-cell stage embryo; endocrine gland; lip; paravertebral ganglion; and thymus primordium. Orthologous to human RAB27A (RAB27A, member RAS oncogene family).
