Genes

Locus	Cultural Requirements	Link Group	Type
cpc-2	VIIR. Linked to arg-10. Right of T(5936). Encodes a protein entirely composed of WD repeat segments. Simultaneously affects both basal levels and the ability to derepress enzymes in arginine and other amino acid biosynthetic pathways. Sensitive to p-fluorophenylalanine and 3-AT. Female sterile.	VIIR	B
cyh-2	VR. Right of lys-2 (<1%). Left of leu-5 (<1 to 2%) and sp(2 to 9%) (496, 818, PB). Resistant to cycloheximide (496, 748). Protein synthesis on mutant ribosomes proceeds in the presence of cycloheximide in a cell-free system (834). Excellent marker. Readily scored on slants with 10 µg of cycloheximide per ml autoclaved in the medium or with 1 µg added after autoclaving. Resistance in heterokaryons has been reported to be dominant (496, 626) or recessive (939); it may depend on nuclear ratios or media. Used in mutagenicity test systems (626). Used to show that the cycloheximide-induced phase shift of the circadian clock involves protein synthesis (738). Double mutant cyh-1;cyh-2grows slowly and is much more insensitive to cycloheximide than either single mutant (496).	VR	B
