UASt regulates expression of rl containing a serine instead of an arginine at position amino acid 80, equivalent to the R68S mutation initially identified in the yeast ERK, Mpk1, which renders Mpk1 intrinsically active. Mutations at the equivalent residue of human ERK1 (R84) and ERK2 (R65) have been found in human tumors.

R80S
Analogous R67I mutation in human MAPK1 and R84H in human MAPK3 implicated in cancer; mutation carried on in vitro construct; site of nucleotide substitution in fly gene inferred by FlyBase curator based on reported amino acid change.
A somatic variant at the analogous site has been found associated with cancer in each of the two paralogous genes in human (MAPK1, MAPK3).
Expressing rlR80S.UAS under the control of Scer\GAL4Bx-MS1096 induces modest yet consistent formation of extra vein material in distal wing positions.

The vestigial wing phenotype induced by the expression of Dsor1GD9123 under the control of Scer\GAL4Bx-MS1096 is only subtly suppressed by the co-expression of rlR80S.UAS.
The pupal lethality of individuals expressing Dsor1GD9123 under the control of Scer\GAL4ey.PH is partially rescued by the co-expression of rlR80S.UAS (majority die), although the adults show a (mostly mild) small eye phenotype.
The wing defects induced by the expression of Ras85DN17.UAS under the control of Scer\GAL4Bx-MS1096 (smaller wing and loss of L3-5 vein material are partially suppressed by the co-expression of rlR80S.UAS (complete suppression in L3, partial suppression in L4 or L5).
scrib1 homozygous eye disc clones that also express rlR80S.UAS under the control of Scer\GAL4Act5C.PI are larger than clones only homozygous for scrib1. Double mutant antennal disc clones are readily detected, unlike scrib1 single mutant clones. Individuals bearing double mutant clones show high abdominal accumulation of clonal cells, which is rare in the scrib1 single mutant clone condition.
