Also Known as RASL; ARHT2; MIRO2; MIRO-2; C16orf39

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 89941

About RHOT2

Cytogenetic location: 16p13.3 Genomic coordinates (GRCh38): 16:668,083-674,174 (from NCBI)

This gene has 28 transcripts (splice variants), 195 orthologues and 22 paralogues. Ubiquitous expression in spleen (RPKM 20.5), duodenum (RPKM 16.0) and 25 other tissues.

Summary

This gene encodes a member of the Rho family of GTPases. The encoded protein is localized to the outer mitochondrial membrane and plays a role in mitochondrial trafficking and fusion-fission dynamics. [provided by RefSeq, Nov 2011]
