enpl-1 encodes the C. elegans ortholog of the Hsp90 family member and endoplasmic reticulum (ER) chaperone GRP94/GP96; loss of enpl-1 activity via RNAi results in slow growth, larval arrest, uncoordinated locomotion, and weak endocytosis defects; in addition, loss of enpl-1 expression results in an increase in hsp-4 expression, revealing compensatory regulation amongst ER chaperones; an enpl-1::gfp reporter fusion is expressed in the pharynx, with large-scale expression studies reporting additional expression in the intestine and several unidentified cells in the head.
Predicted to enable unfolded protein binding activity. Predicted to be involved in protein folding and ubiquitin-dependent ERAD pathway. Predicted to be located in endoplasmic reticulum and perinuclear region of cytoplasm. Expressed in head; neurons; pharynx; and vulva. Human ortholog(s) of this gene implicated in lung adenocarcinoma. Is an ortholog of human HSP90B1 (heat shock protein 90 beta family member 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.
