SNRPD3
small nuclear ribonucleoprotein D3 polypeptide | SMD3, Sm-D3

This gene encodes a core component of the spliceosome, which is a nuclear ribonucleoprotein complex that functions in pre-mRNA splicing. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

SNRPD3 — as a Regulated Gene

TFs regulating SNRPD3 0 TFs

Transcription factors with Perturb-seq knockdown data for SNRPD3. The Binding column indicates whether any binding evidence exists for this TF–gene pair (ChIP-seq or motif footprint peaks). The Mean coef is the average Perturb-seq regression coefficient across active gRNAs (positive = SNRPD3 upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.

Elements linked to SNRPD3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of SNRPD3, linked by TSS proximity or chromatin conformation (Multiome / HiCAR). Each element overlaps at least one TF ChIP-seq binding site — the TFs column shows how many distinct TFs bind that element.
