Anti-PYM1 Rabbit Polyclonal Antibody for WB, IF/ICC, ELISA - Q9BRP8

Core Product Specifications and Parameters

Biological Background: PYM1 Function and Localization

• PYM1, also known as Partner of Y14 and mago, is a key regulator of the exon junction complex (EJC), functioning as an EJC disassembly factor that promotes translation-dependent removal of the EJC from spliced mRNAs.
• It associates with the 40S ribosomal subunit, which likely restricts its EJC disassembly activity to mRNAs undergoing active translation, preventing premature complex disruption.
• PYM1 interferes with nonsense-mediated mRNA decay (NMD) and enhances translation of spliced mRNAs, thereby antagonizing EJC functions post-splicing.
• While PYM1 may bind RNA, the functional relevance of this interaction is unclear; RNA-binding was observed in some studies (PubMed:14968132) but not independently of the EJC in others (PubMed:19410547). Related references: PMID:14968132, PMID:19410547
• The protein localizes to both the cytoplasm and the nucleus, specifically within the nucleolus and nucleoplasm, consistent with its shuttling role in mRNA processing.
• Post-translational modifications include acetylation and phosphorylation, which may regulate its activity or interactions.
• Alternative splicing generates multiple isoforms, adding functional diversity to the PYM1 gene product.

Experimental Guidance and Technical Tips

• The immunogen corresponds to the N-terminal region (aa 1-204) of human PYM1, suggesting the antibody may recognize epitopes within this conserved domain; consider sequence alignment with mouse and rat orthologs to support observed cross-reactivity.
• For Western blotting, PYM1 has a predicted molecular weight of ~23 kDa; validate the observed band size in the relevant sample system and use appropriate loading controls.
• For immunofluorescence/ICC, fixation and permeabilization conditions should be optimized, as PYM1 exhibits both cytoplasmic and nuclear localization; include organelle markers to confirm specificity.
• ELISA applications may be used for qualitative or semi-quantitative detection; consider paired antibody strategies for sandwich immunoassays if quantitative data are required.
• Since the antibody is a polyclonal pool, lot-to-lot consistency should be verified when transitioning between production batches, and working dilutions should be determined empirically for each assay.
