Publication
Insulin receptor substrate 1 binds two novel splice variants of the regulatory subunit of phosphatidylinositol 3-kinase in muscle and brain.
We have identified two novel alternatively spliced forms of the p85alpha regulatory subunit of phosphatidylinositol (PI) 3-kinase by expression screening of a human skeletal muscle library with phosphorylated baculovirus- produced human insulin receptor substrate 1. One form is identical to p85alpha throughout the region which encodes both Src homology 2 (SH2) domains and the inter-SH2 domain/p110 binding region but diverges ... [more]

Additional Notes
- P35568 interacts with P27986-2 where P35568 is the bait and P27986-2 is the hit.
- This experiment differed from a typical far western in that the cell lysate was not run on a gel. cDNA was expressed in bacterial colonies and proteins from bacteria were then bound to a nitrocellulose membrane that was then probed with the protein of interest and positive interactions were visualized by radiography.
