Ribosome-binding protein 1, also referred to as p180, is a protein that in humans is encoded by the RRBP1gene.[1][2]
RRBP1 is a membrane-bound protein found in the endoplasmic reticulum (ER). It was originally identified as the ribosome receptor for the ER,[3] however several groups later demonstrated that this activity did not co-fractionate with RRBP1 [4][5] but rather with Sec61 (i.e. the translocon).[6][7] RRBP1 can enhance the association of certain mRNAs to the endoplasmic reticulum in a manner that does not require ribosome activity, likely by directly associating the mRNA's phosphate backbone[8]. In addition, RRBP1 may promote the association of polysomes with the translocon [9][10] and play a role in ER morphology.[11] RRBP1 may also bind to microtubules.[12] Although the p180 isoform is the most abundant, it may exist in different forms due to removal of tandem repeats by partial intraexonic splicing. RRBP1 has been excluded as a candidate gene in the cause of Alagille syndrome.[2]
