STT3B
STT3 oligosaccharyltransferase complex catalytic subunit B | FLJ90106, SIMP, STT3-B

The protein encoded by this gene is a catalytic subunit of a protein complex that transfers oligosaccharides onto asparagine residues. Defects in this gene are a cause of congenital disorder of glycosylation Ix (CDG1X). [provided by RefSeq, Jun 2014]

STT3B — as a Regulated Gene

TFs regulating STT3B 0 TFs

Transcription factors with Perturb-seq knockdown data for STT3B. 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 = STT3B 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 STT3B

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of STT3B, 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.
