Amino acid replacement: Y182A.
UASt regulatory sequences drive expression of an altered form of Hsap\PABPN1 which encodes 17 alanine residues following the initial methionine, instead of the wild-type number of 10, and which carries two mutations (Y182A and F222A) in the RRM domain.
Amino acid replacement: F222A.
Expression of Hsap\PABPN1dm.17ala.Scer\UAS under the control of Scer\GAL4Mhc.PW causes no, or a very low number of, flies with abnormal wing position. The musculature of these flies appears to be unaffected, and nuclear morphology is normal.
