Ribosome-binding protein 1 also referred to as p180 is a protein that in humans is encoded by the RRBP1 gene.RRBP1 is a membrane-bound protein found in the endoplasmic reticulum (ER). It was originally identified as the ribosome receptor for the ER however several groups later demonstrated that this activity did not co-fractionate with RRBP1 but rather with Sec61 (i.e. the translocon).
