SLC5A3
solute carrier family 5 member 3 | SMIT, SMIT1

Enables myo-inositol:sodium symporter activity; potassium channel regulator activity; and transmembrane transporter binding activity. Predicted to be involved in several processes, including inositol metabolic process; monosaccharide transmembrane transport; and myo-inositol import across plasma membrane. Predicted to act upstream of or within several processes, including positive regulation of protein localization to membrane; positive regulation of reactive oxygen species biosynthetic process; and regulation of respiratory gaseous exchange. Located in perinuclear region of cytoplasm and plasma membrane. [provided by Alliance of Genome Resources, Jul 2025]

SLC5A3 — as a Regulated Gene

TFs regulating SLC5A3 0 TFs

Transcription factors with Perturb-seq knockdown data for SLC5A3. 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 = SLC5A3 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 SLC5A3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of SLC5A3, 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.
