Thereby, plays an important role in the splicing of cellular pre-mRNAs. Most spliceosomal snRNPs contain a common set of Sm proteins SNRPB, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF and SNRPG that assemble in a heptameric protein ring on the Sm site of the small nuclear RNA to form the core snRNP. In the cytosol, the Sm proteins SNRPD1, SNRPD2, SNRPE, SNRPF and SNRPG are trapped in an inactive 6S pICln-Sm complex by the chaperone CLNS1A that controls the assembly of the core snRNP. Dissociation by the SMN complex of CLNS1A from the trapped Sm proteins and their transfer to an SMN-Sm complex triggers the assembly of core snRNPs and their transport to the nucleus. Ensures the correct splicing of U12 intron-containing genes that may be important for normal motor and proprioceptive neurons development. Also required for resolving RNA-DNA hybrids created by RNA polymerase II, that form R-loop in transcription terminal regions, an important step in proper transcription termination. May also play a role in the metabolism of small nucleolar ribonucleoprotein (snoRNPs).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization:\u003c\/strong\u003e Nucleus, gem\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTissue details:\u003c\/strong\u003e Expressed in a wide variety of tissues.

The protein encoded by this gene shares similarity with BRE1 of S. cerevisiae. The protein encoded by this human gene is an E3 ubiquitin ligase that regulates chromosome structure by monoubiquitinating histone H2B. This protein acts as a putative tumor suppressor and positively regulates the p53 tumor suppressor as well as numerous histone H2A and H2B genes. In contrast, this protein also suppresses the expression of several protooncogenes and growth-related genes, including many genes that are induced by epidermal growth factor. This gene selectively suppresses the expression of some genes by interfering with chromatin recruitment of transcription elongation factor SII (TFIIS).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eQuantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.\u003c\/li\u003e \u003cli\u003eIsoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.\u003c\/li\u003e \u003cli\u003eContext-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e compare relative target abundance and apparent size shifts (e.g., isoforms\/PTMs) across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e assess distribution across tissue compartments and compare staining patterns between groups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and compare shifts after stimulation or differentiation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAcross these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eApparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.\u003c\/li\u003e \u003cli\u003eSpecies reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.\u003c\/li\u003e \u003cli\u003eControl concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO\/KD, peptide competition, or independent assays) to support interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eFor antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.\u003c\/p\u003e \u003c!-- Sources (internal): -
