Nucleotide change:

C7245217T

Amino acid change:

P277L | mei-P22-PA

Reported amino acid change:

P264I

Comment:

Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change. Discrepancy in reported residue vs inferred residue is due to differences in reference sequence and is explained by author statement: In the published genome sequence, there is an insertion encoding 13 amino acids (EDSSCAT RRRSLS; MYERS et al. 2000 ) Unclear whether missense mutation is P to I or P to L.

      Homozygous females show 3.2% non-disjunction of the X chromosome. Crossing over in the cu-e and e-ca regions of the 3rd chromosome is reduced to about 50% of wild type, while crossing over in the st-cu region is increased to 156% of wild type.
