Autophosphorylation on serine and threonine residues within the activation loop plays a role in enzyme activation.

Transcript was detected strongly in 0-4 h embryos suggesting that it was maternally deposited. Expression steadily decreased throughout embryogenesis until no transcript was detectable by stage 16. Expression was also detected in the adult head and thorax but not the abdomen.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see GBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
RNAi experiments show that dsRNA targetted at this gene suppresses the Pten-dsRNA-induced cell shape changes in Kc167 cells.
The kinase activity of slpr protein can be activated by C6-ceramide or sphingomyelinase in vivo, and by nM concentrations of natural ceramide in vitro.
Mutant embryos have a "dorsal-open" phenotype. The leading edge cells of the epidermis stretch transiently in the dorso-ventral axis, but the elongation is not maintained and the epidermis ultimately retracts.
