Enables signaling receptor binding activity. Involved in negative regulation of anterograde synaptic vesicle transport; negative regulation of receptor localization to synapse; and positive regulation of ERAD pathway. Located in several cellular components, including Golgi apparatus; perinuclear endoplasmic reticulum; and somatodendritic compartment. Expressed in AVAL; AVAR; and nervous system. Is an ortholog of human CNIH1 (cornichon family AMPA receptor auxiliary protein 1) and CNIH2 (cornichon family AMPA receptor auxiliary protein 2).
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.
