Summaries for MRI1 Gene

Entrez Gene Summary for MRI1 Gene

  • This enzyme functions in the methionine salvage pathway by catalyzing the interconversion of methylthioribose-1-phosphate and methythioribulose-1-phosphate. Elevated expression of the encoded protein is associated with metastatic melanoma and this protein promotes melanoma cell invasion independent of its enzymatic activity. Mutations in this gene may be associated with vanishing white matter disease (VMWD). [provided by RefSeq, Jul 2016]

GeneCards Summary for MRI1 Gene

MRI1 (Methylthioribose-1-Phosphate Isomerase 1) is a Protein Coding gene. Diseases associated with MRI1 include Spinal Cord Melanoma and Visual Agnosia. Among its related pathways are Metabolism and S-methyl-5-thio-alpha-D-ribose 1-phosphate degradation. GO annotations related to this gene include identical protein binding and S-methyl-5-thioribose-1-phosphate isomerase activity.

UniProtKB/Swiss-Prot for MRI1 Gene

  • Catalyzes the interconversion of methylthioribose-1-phosphate (MTR-1-P) into methylthioribulose-1-phosphate (MTRu-1-P). Independently from catalytic activity, promotes cell invasion in response to constitutive RhoA activation by promoting FAK tyrosine phosphorylation and stress fiber turnover.
