CATSPER4
cation channel sperm associated 4

Predicted to enable voltage-gated calcium channel activity. Predicted to be involved in flagellated sperm motility; sodium ion transport; and sperm capacitation. Predicted to act upstream of or within establishment of localization in cell. Predicted to be located in plasma membrane. Predicted to be part of CatSper complex. Predicted to be active in acrosomal vesicle and sperm principal piece. [provided by Alliance of Genome Resources, Jul 2025]

CATSPER4 — as a Regulated Gene

TFs regulating CATSPER4 0 TFs

Transcription factors with Perturb-seq knockdown data for CATSPER4. 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 = CATSPER4 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 CATSPER4

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of CATSPER4, 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.
