- Automated Description
- Enables calcium ion binding activity. Involved in several processes, including IRE1-mediated unfolded protein response; determination of adult lifespan; and hemidesmosome assembly. Located in cytoplasm. Is expressed in several structures, including excretory system; intestine; neurons; pharynx; and sperm. Used to study Parkinson's disease. Human ortholog(s) of this gene implicated in several diseases, including endocrine gland cancer (multiple); gastrointestinal system cancer (multiple); hematologic cancer (multiple); lung cancer (multiple); and thrombocytosis. Orthologous to several human genes including CALR (calreticulin).
- WB Description
- crt-1 encodes an ortholog of calreticulin (a calcium-binding molecularchaperone of the endoplasmic reticulum); crt-1 is dispensable forviability, but required for normal sperm development, male matingefficiency, some forms of necrotic cell death, and hermaphrodite fertilityat high temperatures (which may reflect a stress response); crt-1expression is induced by stress; CRT-1 protein binds Ca(2+) and cansuppress heat-induced protein aggregation in vitro; crt-1(bz29) andcrt-1(bz30) mutants suppress necrotic cell death induced either bymec-4(d) or by a constitutively activated Gas subunit; crt-1(bz29);crt-1's suppression of necrosis is itself partly reversed by thapsigargin,which enhances calcium release from the endoplasmic reticulum;crt-1(bz30), and crt-1(jh101) mutants grow more slowly, and have havereduced broods at 25 deg. C.; crt-1(jh101) mutants are slightly shorterthan normal and have defective sperm; CRT-1 and ITR-1 serve partlyredundant functions in vivo, since crt-1;itr-1(sa73) are highly infertileand slow-growing with greatly slowed defecation; a number of proteins,notably HSP-3/4 and PDI-2/3, are over-expressed in crt-1(jh101) mutantsand crt-1(jh101);cnx-1(nr2009) double mutants.
