Gene Gene information from NCBI Gene database.
Entrez ID 55149
Gene name Mitochondrial poly(A) polymerase
Gene symbol MTPAP
Synonyms (NCBI Gene)
PAPD1SPAX4TENT6
Chromosome 10
Chromosome location 10p11.23
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 201
