Predicted to be located in mitochondrion. Is an ortholog of several human genes including ARMCX1 (armadillo repeat containing X-linked 1); ARMCX2 (armadillo repeat containing X-linked 2); and ARMCX3 (armadillo repeat containing X-linked 3).
Enables ion channel regulator activity. Involved in positive regulation of cell communication by electrical coupling and response to xenobiotic stimulus. Located in axon and gap junction. Expressed in several structures, including enteric muscle; ganglia; head neurons; somatic nervous system; and vulval muscle.
