MTPAP - mitochondrial poly(A) polymerase Gene
Also Known as PAPD1; SPAX4; TENT6
Species: Homo sapiens
About MTPAP
This gene has 5 transcripts (splice variants), 206 orthologues, 4 paralogues and is associated with 2 phenotypes. Ubiquitous expression in bone marrow (RPKM 4.8), testis (RPKM 4.4) and 25 other tissues.
Summary
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]
