Overview

Product nameAnti-Nsr1p antibody [31C4]
-
DescriptionMouse monoclonal [31C4] to Nsr1p
-
Host speciesMouse
-
SpecificityThis antibody was isolated during a screen for mAbs against yeast nucleolar proteins. Specificity was determined by screening a yeast genomic library in lambda gt11. Two individually isolated, different positive clones were found. Sequencing revealed that in both clones beta-galactosidase was fused at the EcoRI site to the amino acid sequence beginning with …EFEH190 in Nsr1p. Thus, it is likely to react with an epitope(s) in the C-terminal 55% of Nsr1p.

Target
-
RelevanceNsr1p is localized in the nucleolus and binds to the single-stranded telomeric repeat sequence (TG1-3)n. It has a role in ribosomal RNA maturation and possibly in transport of proteins into the nucleus.
