MTSS1
MTSS I-BAR domain containing 1 | KIAA0429, MIM, MIMA, MIMB

Enables actin monomer binding activity; identical protein binding activity; and signaling receptor binding activity. Predicted to be involved in several processes, including adherens junction maintenance; positive regulation of actin filament bundle assembly; and renal tubule development. Predicted to act upstream of or within several processes, including actin filament polymerization; bone mineralization; and magnesium ion homeostasis. Located in actin cytoskeleton.

MTSS1 — as a Regulated Gene

TFs regulating MTSS1 0 TFs

Transcription factors with Perturb-seq knockdown data for MTSS1. 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 = MTSS1 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 MTSS1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of MTSS1, 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.
