Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.
Homozygous olfactory receptor neuron (ORN) clones result in complete loss of the Or71a, Or88a, Or42a and Or46a-expressing ORNs and a mild reduction in cell number of the Or10a, Or47a, Or22a, Or47b, Or33c and Or59c ORNs.
Homozygous ORN clones result in defects in glomerulus targeting. Mutant Or47a-expressing ORNs frequently innervate a ventromedial glomerulus (in wild-type animals they target the dorsomedial DM3 glomerulus). Mutant Or59c ORNs show a strong mistargeting phenotype. Mutant Or92a ORNs show a mistargeting phenotype.
Wild-type Or59c, Or42a and Or47a ORNs project normally in a psidin1 background.
Neurons in primary neuron cultures derived from mutant embryos have significantly smaller lamellipodia and significantly longer neurites compared to wild-type controls.
psidin1 mutant larvae are unable to induce Def production.
psidin1/Df(3R)H15 mutants are equally deficient in the induction of Def whether the infection was with a Gram-negative or Gram-positive micro-organism.
psidin1/Df(3R)H15 mutants die after a prolonged third instar larval instar and develop melanotic masses two days after the normal time of pupariation. At this late time point, defects in the blood cells are detected, including necrotic and multinucleate cells. However, none of these defects are apparent at the early wandering stage. psidin1/Df(3R)H15 mutants melanise wound sites normally.
Mutant larvae show normal melanisation at a wound site in response to infection. Mutant larvae have a high frequency of melanotic tumours (penetrance of this phenotype is approximately 80%).

Expression of tsrS3A.Scer\UAS under the control of Scer\GAL4Act.PU reduces the axon mistargeting phenotype seen in Or59c-expressing psidin1 olfactory receptor neuron (ORN) clones by 14%.
Expression of tsrS3E.Scer\UAS under the control of Scer\GAL4Act.PU increases the axon mistargeting phenotype seen in Or59c-expressing psidin1 ORN clones by 8%.
Or59c-expressing ORN clones which are mutant for psidin1 and which are also expressing LIMK1Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Act.PU show mistargeting in 87% of cases.
Expression of either LIMK1JF02063 or LIMK1Scer\UAS.KI.T:Ivir\HA1 under the control of Scer\GAL4Act.PU significantly rescues the axon mistargeting phenotype seen in Or59c-expressing psidin1 ORN clones.
Expression of NAA20KK102646 under the control of Scer\GAL4Act.PU does not enhance the reduction in cell number and axon mistargeting defects seen in Or42a and Or59c ORNs homozygous for psidin1.
Expression of BacA\p35Scer\UAS.cUa under the control of Scer\GAL4Act.PU rescues the reduction in cell number but not the axon mistargeting phenotypes seen in psidin1 Or59c olfactory receptor neuron clones.

Expression of psidinIG978.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Act.PU fully rescues the cell loss phenotype seen in Or59c ORN clones which are homozygous for psidin1, but the axon targeting defects of these ORNs are only partially rescued.
Expression of psidinS678D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Act.PU fully rescues the axon targeting defects seen in Or59c ORN clones which are homozygous for psidin1, but the cell loss phenotype of these ORNs is not rescued.
