Synapse - Interactions of proteins with an established role in the presynapse. Extracts of p65PI3K and p85alpha-expressing CTLL2 cells were incubated with the control column or a Ras-peptide column. After washing, retained material was recovered by boiling beads in SDS sample buffer, resolved by SDS-PAGE, and examined by Western blot. acarrera@cnb.uam.es J. Biol. Chem.

A p65 isoform of Pik3r1 was also shown to interact with PTPN6 but this isoform could not be matched to any sequence in the UniProt database at the time of curation. hras-pik3r1 HRas peptide (aa 17-42) pulls down p85alpha in vitro 679874 n/a 679877 unspecified role unspecified role bait bait region sufficient to bind sufficient binding region sufficient to bind certain certain sequence position certain certain certain sequence position certain false chemical synthesis Chemical synthesis (Chemical synthesis) N/A 679875 unspecified role unspecified role prey prey region ha tag ha tag YPYDVPDYA epitope tag YPYDVPDYA epitope tag undetermined undetermined sequence position undetermined undetermined undetermined sequence position undetermined false mouse-ctll_2 Mus musculus CTLL-2 C57b1/6 T cell lymphoblasts ctll_2 CTLL-2 mouse C57b1/6 T cell lymphoblasts physical association physical association false false false 5 A p65 isoform of Pik3r1 (P26450) was also shown to bind but this could not be matched to any sequence in UniProt at the time of annotation.
