The increased number of intestinal progenitor cells in mitosis characteristic for adult flies expressing Ret^{Scer\UAS.T:Zzzz\FLAG,T:Zzzz\His6} driven by Scer\GAL4^esg-NP7397 (combined with tub-Gal80[ts] for temporal control) is suppressed by co-expression of Fak^{Scer\UAS.T:Ivir\HA1}.

Heterozygous Fak^CG1 enhances the ommatidial mis-patterning seen in eyes expressing Ret^GMR.PR. Homozygous Fak^CG1 causes a smaller eye due to a completely disrupted ommatidial pattern. This enhancement is reversed upon co-expression of either Fak^{Scer\UAS.T:Ivir\HA1} or Fak^{Y430F.Scer\UAS} under the control of Scer\GAL4^GMR.PU.

Expression of Ret^GMR.PR partially suppresses the reduction in eye size seen in flies expressing hid^GMR.PG. This suppression is partially reversed when Fak^{Scer\UAS.T:Ivir\HA1} is expressed under the control of Scer\GAL4^GMR.PU.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^GMR.PU partially suppresses the small eye size induced by expression of one copy of Ret^MEN2A.GMR.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^GMR.PU suppresses the rough eye phenotype seen upon expression of Ret^GMR.PR. The reduction in retinal apoptosis is also rescued.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} suppresses the partial lethality seen when Ret^{MEN2A.Scer\UAS} is expressed under the control of Scer\GAL4^ptc-559.1. The proportion of surviving flies rises from 46% to 92%. The wing vein and male genitalia defects seen in adult flies are also suppressed.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^GMR.PU does not have a significant effect on the reduced eye size seen upon expression of hid^GMR.PG.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^GMR.PU partially suppresses the eye size defect and ectopic cone cell phenotype induced by expression of two copies of Ret^MEN2A.GMR, resulting in the reappearance of normal ommatidial cores and surrounding interommatidial cells in pupal retinas.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} does not suppress the eye phenotypes seen when phl^{Scer\UAS.F179} is expressed under the control of Scer\GAL4^sev.PU.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} suppresses the reduction in eye size seen in flies expressing Egfr^Scer\UAS.cBa under the control of Scer\GAL4^GMR.PU.

Expression of Fak^{Scer\UAS.T:Ivir\HA1} partially suppresses the almost total lethality seen when Egfr^Scer\UAS.cBa is expressed under the control of Scer\GAL4^ptc-559.1. The proportion of surviving flies is increased to approximately 60%.

The defects seen in the Fas2-positive longitudinal fascicles of embryos expressing Fak^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^sca-537.4 are partially suppressed if the embryos are also heterozygous for Sema-1a^k13702.

The penetrance of the wing blistering phenotype seen in females expressing Fak56D^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^en-e16E at 25^oC is increased from 28% to 44% and 40% if they are carrying mys⁸/+ or mys^b43/+ respectively. Males expressing Fak56D^{Scer\UAS.T:Ivir\HA1} under the control of Scer\GAL4^en-e16E at 25^oC and hemizygous for either mys⁸ or mys^b43 show 31% and 21% wing blistering respectively (compared to 0% wing blistering in a mys⁺ background).

The inhibition of border cell migration seen in the ovaries of jar^a.Scer\UAS; Scer\GAL4^slbo.2.6 flies is significantly suppressed by the presence of shg^hs.PW under heat shock condition (flies raised at 29^oC and given a 1 hour heat shock at 37^oC 6-10 hours prior to dissection.). Partial suppression is also seen in flies carrying slbo^Scer\UAS.cLa or shg^Scer\UAS.cSa, but not Fak56D^{Scer\UAS.T:Ivir\HA1}.
