A H53Y missense mutation in the RF domain, which is expected to severely disrupt the RF and compromise Su(z)2 function.
Amino acid replacement: H53Y.

H53Y | Su(z)2-PA; H53Y | Su(z)2-PB; H53Y | Su(z)2-PC
H53Y
Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
One copy of Su(z)2e26 is unable to suppress position effect variegation (PEV) at the w locus caused by In(1)wm4.
One copy of Su(z)2e26 weakly suppresses the telomeric position effect (TPE) in stocks carrying a variegating P{hsp26-pt-T}39C-5 insertion at the telomere of the left arm of chromosome two.
Suppresses z1 eye color.
Complementation behavior is complex: this allele is only tentatively assigned to Su(z)3.
