Enables ubiquitin protein ligase binding activity. Involved in negative regulation of axon extension and positive regulation of synapse assembly. Located in presynaptic active zone. Expressed in mechanosensory neurons; motor neurons; muscle cell; nerve ring neurons; and pharynx.
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.
