Summaries for MTPAP Gene

Entrez Gene Summary for MTPAP Gene

  • The protein encoded by this gene is a member of the DNA polymerase type-B-like family. This enzyme synthesizes the 3' poly(A) tail of mitochondrial transcripts and plays a role in replication-dependent histone mRNA degradation.[provided by RefSeq, Jan 2011]

GeneCards Summary for MTPAP Gene

MTPAP (Mitochondrial Poly(A) Polymerase) is a Protein Coding gene. Diseases associated with MTPAP include Ataxia, Spastic, 4 and Spastic Ataxia. GO annotations related to this gene include poly(A) RNA binding and identical protein binding. An important paralog of this gene is TUT1.

UniProtKB/Swiss-Prot for MTPAP Gene

  • Polymerase that creates the 3 poly(A) tail of mitochondrial transcripts. Can use all four nucleotides, but has higher activity with ATP and UTP (in vitro). Plays a role in replication-dependent histone mRNA degradation. May be involved in the terminal uridylation of mature histone mRNAs before their degradation is initiated. Might be responsible for the creation of some UAA stop codons which are not encoded in mtDNA.

Note=The disease is caused by mutations affecting the gene represented in this entry. MTPAP mutations result in a defect of mitochondrial mRNA maturation. Affected individuals exhibit a drastic decrease in poly(A) tail length of mitochondrial mRNA transcripts, including COX1 and RNA14 (PubMed:20970105). {ECO:0000269 PubMed:20970105}.
