Subunit Structure
Associates (via SH2 domain) with activated EGF receptors (tyrosine phosphorylated). Interacts with PDGFRA (tyrosine phosphorylated); the interaction may be indirect. Also associates to other cellular Tyr-phosphorylated proteins such as SIT1, IRS1, IRS4, SHC and LNK; probably via the concerted action of both its SH2 and SH3 domains. It also seems to interact with RAS in the signaling pathway leading to DNA synthesis. Binds to and translocates the guanine nucleotide exchange factors SOS. Interacts with phosphorylated TOM1L1 and MET. Interacts with the phosphorylated C-terminus of SH2B2. Interacts with phosphorylated SIT1, LAX1, LAT, LAT2 and LIME1 upon TCR and/or BCR activation. Interacts with PTPNS1, REPS2 and the syntrophin SNTA1. Interacts with REPS1 and PIK3C2B via its SH3 domains. Interacts with CBL and CBLB. Interacts with AJUBA. Interacts with SHB, INPP5D/SHIP1, SKAP1 and SKAP2 (By similarity). Interacts with CLNK. Forms a complex with MUC1 and SOS1, through interaction of the SH3 domains with SOS1 and the SH2 domain with phosphorylated MUC1. Interacts with PRNP (By similarity). Interacts with NISCH and RALGPS1 (By similarity). Interacts also with HCST. Interacts with GAPT and PTPRE. Interacts (via SH2 domain) with KIF26A (By similarity). Interacts with THEMIS. Interacts (via SH3 2) with GAB2. Interacts with ADAM15. Interacts with PTPRJ and BCR. Interacts with PTPN23. Interacts with FLT4 (tyrosine phosphorylated) (By similarity). Part of a complex including TNK2, GRB2 and one receptor tyrosine kinase (RTK) such as AXL, in which GRB2 promotes RTK recruitment by TNK2 (By similarity). Interacts with NTRK1 (phosphorylated upon ligand-binding). Interacts with PTK2B/PYK2 (tyrosine phosphorylated) (By similarity). Interacts with KDR. Interacts with FLT1 (tyrosine-phosphorylated). Interacts with THEMIS2. Interacts (via SH2 domain) with AXL and KIT (phosphorylated). Interacts with EPHB1 and SHC1; activates the MAPK/ERK cascade to regulate cell migration. Interacts with PTPN11. Interacts (via SH2 domain) with CSF1R (tyrosine phosphorylated). Interacts (via SH2 domain) with TEK/TIE2 (tyrosine phosphorylated). Interacts with PTK2/FAK1 (tyrosine phosphorylated). Interacts with SCIMP. Interacts with TESPA1. Interacts (via SH3 domains) with GAREM1 (via proline-rich domain and tyrosine phosphorylated); the interaction occurs upon EGF stimulation. Interacts with ASAP3 (phosphorylated form). Interacts with CD28 (By similarity). Interacts with PLCG1, LAT and THEMIS upon TCR activation in thymocytes; the association is weaker in the absence of TESPA1. Interacts with DAB2. Interacts with RAB13; may recruit RAB13 to the leading edge of migrating endothelial cells where it can activate RHOA. UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
