During spliceosome assembly, splicing factor 1 (SF1) specifically recognizes the intron branch point sequence (BPS) UACUAAC in the pre-mRNA transcripts. We show that the KH-QUA2 region of SF1 defines an enlarged KH (hn RNP K) fold which is necessary and sufficient for BPS binding. The 3' part of the BPS (UAAC), including the conserved branch point adenosine(More)
The cell-surface glycoprotein vascular cell adhesion molecule-1 (VCAM-1; ref. 1) mediates intercellular adhesion by specific binding to the integrin very-late antigen-4 (VLA-4, alpha 4 beta 1; ref. 3). VCAM-1, with the intercellular adhesion molecules ICAM-1, ICAM-2, ICAM-3 and the mucosal vascular addressin MAd-CAM-1, forms an integrin-binding subgroup of(More)
Quality control within the endoplasmic reticulum (ER) is thought to be mediated by the interaction of a folding protein with one or several resident ER proteins [1]. Protein disulphide isomerase (PDI) is one such ER resident protein that has been previously shown to interact with proteins during their folding and assembly pathways [2, 3]. It has been(More)
