About ISYNA1

Cytogenetic location: 19p13.11 Genomic coordinates (GRCh38): 19:18,434,388-18,438,133 (from NCBI)

This gene has 14 transcripts (splice variants) and 208 orthologues. Broad expression in testis (RPKM 72.6), placenta (RPKM 57.0) and 14 other tissues.

Summary

This gene encodes an inositol-3-phosphate synthase enzyme. The encoded protein plays a critical role in the myo-inositol biosynthesis pathway by catalyzing the rate-limiting conversion of glucose 6-phosphate to myoinositol 1-phosphate. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the short arm of chromosome 4.
