X:11,072,713..11,072,713 [-]
Nucleotide change:

T11072713A

Amino acid change:

C2271S | sev-PA

Reported amino acid change:

C2276S

Comment:

Amino acid replacement reported as reported as Cys to Ser, which could result from a nucleotide substitution in the first or second base of the codon. The mutation was annotated at the first base of the codon. One of two amino acid changes observed in sev in mutant strain.

X:11,072,201..11,072,201 [-]
Nucleotide change:

C11072201T

Amino acid change:

T2422I | sev-PA

Reported amino acid change:

T2427I

Comment:

One of two amino acid changes observed in the sev[AE2} mutant strain. Because of evolutionary conservation at this position, this amino acid change is thought to be responsible for the phenotype. The site of nucleotide substitution in the mutant was inferred by FlyBase based on the reported amino acid change.
