Enzyme Name (EC)

hypoxia-inducible factor-proline dioxygenase (1.14.11.29)

Gene Summary

HIF prolyl hydroxylase (Hph) encodes the prolyl-4 hydroxylase that hydroxylases proline 850a of the product of sima, which is the alpha-subunit of the hypoxia inducible factor (HIF). The product of Hph regulates growth through both independent and dependent mechanisms of the product of sima. [Date last reviewed: 2019-03-07] (FlyBase Gene Snapshot)

Gene Group (FlyBase)

PEPTIDYL-PROLINE DIOXYGENASES -: Peptidyl-proline dioxygenases catalyze the hydroxylation of peptidyl L-proline to peptidyl hydroxy-L-proline, where 2-oxoglutarate and one other act as hydrogen or electron donors with incorporation of one atom of oxygen into each donor.

Summary (Interactive Fly)

oxygen sensor - a specific prolyl-4-hydroxylases required for hydroxylation of key prolyl residues in the HIFα sequence - Fe (II) and 2-oxoglutarate dependent dioxygenase superfamily protein that uses O2 as a co-substrate for catalysis - involved in tracheal development, oogenesis and drives cell growth downstream of Cyclin D

Model Confidence:

Very high (pLDDT > 90)
Confident (90 > pLDDT > 70)
Low (70 > pLDDT > 50)
Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Sequence Crossreferences

NCBI Gene - Gene integrates information from a wide range of species. A record may include nomenclature, Reference Sequences (RefSeqs), maps, pathways, variations, phenotypes, and links to genome-, phenotype-, and locus-specific resources worldwide.

40633

GenBank Nucleotide - A collection of sequences from several sources, including GenBank, RefSeq, TPA, and PDB.

GenBank Protein - A collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB.

RefSeq - A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein.

UniProt/GCRP - The gene-centric reference proteome (GCRP) provides a 1:1 mapping between genes and UniProt accessions in which a single 'canonical' isoform represents the product(s) of each protein-coding gene.

Q8SX21

UniProt/TrEMBL - Automatically annotated and unreviewed records of protein sequence and functional information
