MTPN - myotrophin Gene
Also Known as V-1; GCDP
Species: Homo sapiens
About MTPN
This gene has 2 transcripts (splice variants), 194 orthologues and 1 paralogue. Ubiquitous expression in brain (RPKM 74.6), esophagus (RPKM 68.4) and 24 other tissues.
Summary
The transcript produced from this gene is bi-cistronic and can encode both myotrophin and leucine zipper protein 6. The myotrophin protein is associated with cardiac hypertrophy, where it is involved in the conversion of NFkappa B p50-p65 heterodimers to p50-p50 and p65-p65 homodimers. This protein also has a potential function in cerebellar morphogenesis, and it may be involved in the differentiation of cerebellar neurons, particularly of granule cells. A cryptic ORF at the 3' end of this transcript uses a novel internal ribosome entry site and a non-AUG translation initiation codon to produce leucine zipper protein 6, a 6.4 kDa tumor antigen that is associated with myeloproliferative disease.
