vem-1 encodes a transmembrane protein that contains a cytochrome b5-like heme/steroid-binding domain and is orthologous to mammalian VEMA, a membrane-associated progesterone receptor component; in C. elegans, vem-1 is required for proper axonal guidance of ventral nerve cord neurons; vem-1 interacts genetically with unc-40, whose protein product also interacts with VEM-1; a VEM-1::GFP reporter fusion is expressed from embryonic stages through late larval stages and is found in a subset of neurons, including the AVG pioneer neurons, that extend processes into the ventral nerve cord; microarray experiments indicate that vem-1 transcripts are upregulated in response to treatment with xenobiotics such as clofibrate and beta-naphthoflavone.
Involved in innate immune response. Located in axon. Expressed in AVG; head neurons; and somatic nervous system. Is an ortholog of human PGRMC1 (progesterone receptor membrane component 1).
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.
