Gene Snapshot
carnation (car) encodes a subunit of the conserved HOPS complex, which is required for pigment granule formation and membrane fusion events, such as fusions between endosomes or autophagosomes with lysosomes. car loss of function mutant flies exhibit altered eye color.

Gene Group (FlyBase)
SM TRAFFICKING GENES -
Members of the Sec1/Munc18 (SM) gene family interact with soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) to regulate SNARE complex assembly and vesicle membrane fusion. (Adapted from PMID:20471239).
VPS-C COMPLEXES: HOPS AND CORVET -
The heterohexameric VPS-C complexes, HOPS and CORVET have been extensively characterised in yeast. They interact with SNAREs and Rabs to promote vesicle tethering. The CORVET complex is involved in early endosome fusion, interacting with Rab5-GTP. The HOPS complex interacts with Rab7-GTP on late endosomes (multivesicular bodies) to promote fusion with the lysosomal compartment (and vacuoles) and also autophagosome-lysosome fusion. The VPS-C complexes share common subunits and CORVET to HOPS conversion intermediates (i-CORVET and i-HOPS) have been proposed to accompany early to late endosome maturation. (Adapted from PMID:19575650 and FBrf0223135).
Protein Function (UniProtKB)
Required for the biogenesis of eye pigment granules (PubMed:10549280). Plays a role in vesicle-mediated protein trafficking to lysosomal compartments and in membrane docking/fusion reactions of late endosomes/lysosomes probably as part of the class C core vacuole/endosome tethering (CORVET) complex (PubMed:10549280, PubMed:22160599, PubMed:27253064).

Phenotypic Description (Red Book; Lindsley and Zimm 1992)
car: carnation
Eye color dark ruby. Body shape and proportions seem rounded. With st, eye color is yellow-brown; with bw, brownish yellow to brown (Mainx, 1938, Z. Indukt. Abstamm. Vererbungsl. 75: 256-76). Malpighian tubes pale yellow in mature larva (Beadle, 1937, Genetics 22: 587-611) but hard to distinguish from wild type before third instar. Eye color autonomous in transplant into wild-type host (Beadle and Ephrussi, 1936, Genetics 21: 230). car dor is pupal lethal and shows reduced recovery in gynandromorphs with male parts car dor (Nash, 1971, DIS 47: 73). car lt also lethal, dies as larva when mother car;lt/+ or car/+;lt and as pupa when mother car/+;lt/+ (Nickla, 1977, Nature 268: 638-39); lethal focus domineering; fate maps to ventral nervous system (Nickla, Lilly, and McCarthy, 1980, Experientia 36: 402-05). Brain histology abnormal [McCarthy and Nickla, 1980, Experientia 36: 1361-63 (fig.)].
