Summary

SHPK (sedoheptulokinase, HGNC:1492) is a protein-coding gene on chromosome 17p13.2, encoding Sedoheptulokinase (Q9UHJ6). Acts as a modulator of macrophage activation through control of glucose metabolism.

The protein encoded by this gene has weak homology to several carbohydrate kinases, a class of proteins involved in the phosphorylation of sugars as they enter a cell, inhibiting return across the cell membrane. Sequence variation between this novel gene and known carbohydrate kinases suggests the possibility of a different substrate, cofactor or changes in kinetic properties distinguishing it from other carbohydrate kinases. The gene resides in a region commonly deleted in cystinosis patients, suggesting a role as a modifier for the cystinosis phenotype. The genomic region is also rich in Alu repetitive sequences, frequently involved in chromosomal rearrangements.
