MICU2
mitochondrial calcium uptake 2 | EFHA1

Enables several functions, including calcium channel regulator activity; calcium ion sensor activity; and protein heterodimerization activity. Involved in calcium import into the mitochondrion; cellular response to calcium ion; and negative regulation of mitochondrial calcium ion concentration. Located in mitochondrial intermembrane space. Part of uniplex complex. Is active in mitochondrial inner membrane. [provided by Alliance of Genome Resources, Jul 2025]

MICU2 — as a Regulated Gene

TFs regulating MICU2 0 TFs

Transcription factors with Perturb-seq knockdown data for MICU2. 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 = MICU2 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 MICU2

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of MICU2, 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.
