MCU
mitochondrial calcium uniporter | FLJ46135, C10orf42, CCDC109A

Enables calcium channel activity; identical protein binding activity; and uniporter activity. Involved in several processes, including cellular response to calcium ion starvation; positive regulation of mitochondrial calcium ion concentration; and positive regulation of mitochondrial fission. Located in mitochondrion. Part of uniplex complex. Is active in mitochondrial inner membrane. [provided by Alliance of Genome Resources, Jul 2025]

MCU — as a Regulated Gene

TFs regulating MCU 0 TFs

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

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