Interleukin-2 receptor subunit beta - IL2RB - Homo sapiens | |||||||
| LIG_SH2_III | 531 | 540 | Binary | Physicochemical compatibility | Phosphorylation of Y536 in the SH2-binding motif of Interleukin-2 receptor subunit beta (IL2RB) induces binding to the Signal transducer and activator of transcription 5A (STAT5A) protein. | ||
Prolactin receptor - PRLR - Homo sapiens | |||||||
| LIG_SH2_STAT5 | 342 | 345 | Binary | Pre‑translational | Alternative Splicing removes the degron motif of Prolactin receptor (PRLR), abrogating binding to Signal transducer and activator of transcription 5A (STAT5A). The PRLR S1a (Isoform Short form 1a of Prolactin receptor (PRLR)) and S1b and (Isoform Short form 1b of Prolactin receptor (PRLR)) isoforms were unable to mediate the transcriptional activation of the beta-casein promoter via the JAK-STAT5 pathway. Therefore these two splice variants act as dominant negatives on the full-length version LF (Isoform 1 of Prolactin receptor (PRLR)). Another study showed that different splice variants of heterodimers (e.g. LF/S1a, LF/S1b) that were able to induce JAK2 phosphorylation but not further signalling events due to lack of STAT recruitment (Qazi et al. (2006) (here)). | ||
Signal transducer and activator of transcription 5A - STAT5A - Homo sapiens | |||||||
| LIG_SH2_III | 686 | 702 | Binary | Physicochemical compatibility | Phosphorylation of Y694 in the SH2-binding motif of Signal transducer and activator of transcription 5A (STAT5A) induces binding to the Signal transducer and activator of transcription 5B (STAT5B) protein. | ||
| LIG_SH2_STAT5 | 694 | 697 | Binary | Pre‑translational | Alternative splicing removes the regulatory Y694 residue of Signal transducer and activator of transcription 5A (STAT5A). The phosphorylation of Y694 by Proto-oncogene tyrosine-protein kinase Src (SRC) has been shown to be essential for DNA binding. This event acts as an important regulatory mechanism (See Clark et al. (2005) (here) and Okutani et al. (2001) (here)). The exact function of Y694 remains uncertain as is binding to STAT5 in dimer. The STAT5A-DeltaE18 does not enter nucleus upon PRLR stimulation. | ||
