Enables D2 dopamine receptor binding activity. Involved in cellular response to paraquat; negative regulation of response to oxidative stress; and regulation of dopamine uptake involved in synaptic transmission. Located in neuron projection; perinuclear region of cytoplasm; and plasma membrane. Expressed in several structures, including NSM; body wall musculature; dopaminergic neurons; hermaphrodite gonad; and vulva. Used to study Parkinson's disease. Human ortholog(s) of this gene implicated in non-syndromic X-linked intellectual disability 58. Is an ortholog of human TSPAN3 (tetraspanin 3) and TSPAN7 (tetraspanin 7).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
