CFAP221
cilia and flagella associated protein 221 | FAP221, PCDP1

Predicted to enable calmodulin binding activity. Predicted to be involved in motile cilium assembly. Predicted to act upstream of or within epithelial cilium movement involved in extracellular fluid movement; establishment of localization in cell; and sperm flagellum assembly. Predicted to be located in axoneme and manchette. Predicted to be active in 9+2 motile cilium. [provided by Alliance of Genome Resources, Jul 2025]

CFAP221 — as a Regulated Gene

TFs regulating CFAP221 0 TFs

Transcription factors with Perturb-seq knockdown data for CFAP221. 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 = CFAP221 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 CFAP221

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of CFAP221, 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.
