This name is given to a variety of proteins and there is scope for considerable ambiguity.
1. A component of the NFκB signalling network that activates NFκB, leading to an increase in expression of mdm2 which inhibits p53. Has been suggested as a prognostic marker for glioblastoma, high levels being associated with poor outlook.
2. Receptor-interacting protein-140 (RIP140, nuclear receptor interacting protein 1, NRIP1, 1158 aa) associates with a transcriptional activation domain of the oestrogen receptor in the presence of oestrogen.
3. Eukaryotic initiation factor 3 (eIF3) is TGFβ receptor interacting protein 1 (TRIP1, 325 aa).
4. Nuclear receptor coactivator 2 is glucocorticoid receptor-interacting protein 1 (GRIP1).
5. GRIP1 is also used for glutamate receptor-interacting protein 1 (1128 aa).
6. There is a receptor-interacting protein 1 (620 aa) associated with the leucine-rich repeat Ig domain-containing Nogo receptor.
7. Another RIP1 interacts specifically with the C-terminal tail of the angiotensin II type 2 receptor (angiotensin II type 2 receptor-interacting protein 1, ATIP1).
8. There is a CB1 cannabinoid receptor-interacting protein 1 (CRIP-1, 164 aa).
9. Thyroid hormone receptor associated protein 1 (TRIP1, 406 aa) is the 26S protease regulatory subunit 8 (proteasome 26S subunit ATPase 5).
10. See receptor interacting protein kinase 1.
