Interacts (via C-terminus) with dock/dreadlocks; this interaction is independent of insulin stimulation and is required for dephosphorylation of the insulin-like receptor InR.
Contains 5 Potential PXXP motifs that may mediate interaction with the SH3 domains of dock/dreadlocks.

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
Comment: maternally deposited
Ptp61F mRNA is expressed at low levels around the niche and in the hub, germline stem cells, and cyst progenitor cells (also called somatic cyst stem cells or CySCs). It is more strongly expressed in differentiating germ cells and somatic cells.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
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 JBrowse 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.
polyclonal
Ptp61F negatively regulates JAK/STAT signaling and is also a transcriptional target of JAK/STAT signaling.
S2-derived S2-NP cells treated with dsRNA made from templates generated with primers directed against Ptp61F experience a more than four-fold increase in Stat92E-dependent reporter activity and a significant increase in Stat92E phosphorylation. dsRNA knock-down also results in a dramatic increase in tyrosine phosphorylation of hop protein.
dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
Area matching Drosophila EST AA567483 (inverted).
The spatial and temporal expression of two alternative transcripts of Ptp61F during Drosophila embryogenesis has been analysed in wild-type embryos and in embryos mutant for pair-rule and segment-polarity genes.
Spatial and temporal transcript accumulation pattern in ovaries is determined by in situ hybridisation.
Two 3' splice variants of this gene generate two proteins that differ in their C-termini. One is targeted to the cytoplasmic membrane, the other to the nucleus.
