Target data

Function

Associated component of the WMM complex, a complex that mediates N6-methyladenosine (m6A) methylation of RNAs, a modification that plays a role in the efficiency of mRNA splicing and RNA processing (PubMed:29507755). Required for accumulation of METTL3 and METTL14 to nuclear speckle (PubMed:24316715, PubMed:24407421, PubMed:24981863). Acts as a mRNA splicing regulator (PubMed:12444081). Regulates G2/M cell-cycle transition by binding to the 3' UTR of CCNA2, which enhances its stability (PubMed:17088532). Impairs WT1 DNA-binding ability and inhibits expression of WT1 target genes (PubMed:17095724).

Supplementary info

Activity summary

WTAP also known as Wilms tumor 1-associated protein is a core component of the writer complex that catalyzes N6-methyladenosine (m6A) methylation on mRNA. With a molecular mass of approximately 39 kDa WTAP localizes almost ubiquitously in human tissues but shows higher expression in liver and kidney cells. This protein assists in the regulation of mRNA splicing and stability functioning as an adapter for RNA binding proteins.

Biological function summary

This protein plays a critical role in post-transcriptional gene regulation by being part of the m6A methyltransferase complex which includes other important proteins like METTL3 and METTL14. WTAP does not bind RNA directly but helps its partners achieve target specificity during gene expression processes. The presence of WTAP within the complex stabilizes and coordinates the activity of the entire methyltransferase assembly.

Pathways

The m6A methylation WTAP facilitates affects various pathways including mRNA splicing and degradation. This process intricately connects WTAP to the regulation of the JAK-STAT signaling pathway where its activity influences inflammatory responses and cell proliferation. Additionally WTAP has ties to the Wnt/β-catenin pathway collaborating with proteins like METTL3 to regulate gene expression involved in cell fate determination and embryogenesis.

Associated diseases and disorders

Research shows WTAP has connections to various cancers such as hepatocellular carcinoma due to its role in mRNA processing and stability. This association often involves its interaction with other oncogenic proteins like METTL3 leading to aberrant gene expression patterns. WTAP also has relevance in acute myeloid leukemia where it influences mRNA maturation and impacts cell differentiation and proliferation.
