CHRNA3
CHRNA3, the cholinergic receptor nicotinic alpha 3 gene at 15q25.1 in the CHRNA5-A3-B4 cluster, encodes the α3 nicotinic acetylcholine receptor subunit, key to ganglionic transmission, nicotine dependence genetics, and CAKUT-dysautonomia.
CHRNA4
CHRNA4 (cholinergic receptor nicotinic alpha 4 subunit, HGNC:1958) is a human chromosome 20 gene encoding the alpha-4 nicotinic acetylcholine receptor subunit; gain-of-function mutations cause sleep-related hypermotor epilepsy and variants affect nicotine dependence.
CHRNA5
CHRNA5 (LNCR2), chromosome 15q25.1 gene encoding the α5 nicotinic acetylcholine receptor subunit; its rs16969968 D398N variant predicts nicotine dependence, smoking cessation age, and lung cancer risk in Europeans.
CHRNA7
CHRNA7 (a7nAChR, HGNC:1960) is the human chromosome 15q13.3 gene encoding the alpha-7 nicotinic acetylcholine receptor subunit, a homopentameric calcium-permeable ion channel; its partial duplication formed the human-specific dominant-negative gene CHRFAM7A.
Chroicocephalus
Chroicocephalus (Eyton, 1836) is a gull genus of the masked-gull clade in Laridae, revived after Pons et al. 2005 mtDNA work showed Larus paraphyletic; includes Black-headed, Bonaparte's, Gray-hooded, Slender-billed, Silver, and Andean Gulls.
Chromafenozide
Chromafenozide (ANS-118) is a dibenzoylhydrazine, non-steroidal ecdysone agonist insecticide from Nippon Kayaku and Sankyo, lepidopteran-specific, sold as MATRIC; EU-approved 2015, approval expired 31 March 2025 without renewal.
Chromaffin cell
Chromaffin cell: neuroendocrine cell of the adrenal medulla and paraganglia, named by Alfred Kohn for chromium staining; neural crest-derived, secretes epinephrine and norepinephrine for the fight-or-flight response.
Chromaffin cell of adrenal gland
Adrenal chromaffin cell (chromaffin cells, adrenal medulla): neural crest-derived neuroendocrine cell storing epinephrine and norepinephrine vesicles, triggered by splanchnic acetylcholine and PACAP during stress; origin revised to Schwann cell precursors.
Chromate transporter, long chain
Long-chain chromate transporter (LCHR, InterPro IPR014047): bidomain ~400-aa branch of the CHR superfamily, including ChrA efflux pumps with 10 transmembrane segments in a 4+6 arrangement that export toxic chromate using the proton motive force.
Chromatin
Chromatin: the DNA, RNA, and protein complex forming eukaryotic chromosomes; DNA wraps around histones in nucleosomes, packaging roughly 2 m of human DNA into a 5-10 micrometer nucleus and regulating gene access.
Chromatin accessibility assay
A chromatin accessibility assay measures which genome regions are physically open in a cell population, identifying regulatory elements where transcription factors and other DNA-binding proteins can access DNA.
