The protein encoded by this gene belongs to the heat shock protein 70 family. This gene uses alternative transcription start sites. A cis-acting segment found in the 5' UTR is involved in stress-dependent induction, resulting in the accumulation of this protein in the endoplasmic reticulum (ER) under hypoxic conditions. The protein encoded by this gene is thought to play an important role in protein folding and secretion in the ER. Since suppression of the protein is associated with accelerated apoptosis, it is also suggested to have an important cytoprotective role in hypoxia-induced cellular perturbation. This protein has been shown to be up-regulated in tumors, especially in breast tumors, and thus it is associated with tumor invasiveness. This gene also has an alternative translation initiation site, resulting in a protein that lacks the N-terminal signal peptide. This signal peptide-lacking protein, which is only 3 amino acids shorter than the mature protein in the ER, is thought to have a housekeeping function in the cytosol. In rat, this protein localizes to both the ER by a carboxy-terminal peptide sequence and to mitochondria by an amino-terminal targeting signal. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014].

Hypoxia up-regulated protein 1 is a protein that in humans is encoded by the HYOU1 gene.

The protein encoded by this gene belongs to the heat shock protein 70 family. This gene has three mRNAs from the use of alternative transcription sites. A cis-acting segment is found at the 5' end of exon 1A which is involved in the stress-dependent induction. The transcript that begins with exon 1B is preferentially induced by hypoxia, resulting in the accumulation of this protein in the endoplasmic reticulum (ER).
