TPPP
tubulin polymerization promoting protein | TPPP/p25, TPPP1, p25, p25alpha

Enables several functions, including magnesium ion binding activity; microtubule nucleator activity; and protein homodimerization activity. Involved in several processes, including microtubule cytoskeleton organization; negative regulation of tubulin deacetylation; and positive regulation of protein polymerization. Located in several cellular components, including cytoskeleton; mitochondrion; and perinuclear region of cytoplasm. Is active in Golgi apparatus. [provided by Alliance of Genome Resources, Apr 2025]

TPPP — as a Regulated Gene

TFs regulating TPPP 0 TFs

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

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