Prolyl 4-hydroxylase, transmembrane is a protein that in humans is encoded by the P4HTM gene. [5]
The product of this gene belongs to the family of prolyl 4-hydroxylases. This protein is a prolyl hydroxylase that may be involved in the degradation of hypoxia-inducible transcription factors under normoxia. It plays a role in adaptation to hypoxia and may be related to cellular oxygen sensing. Alternatively spliced variants encoding different isoforms have been identified.
Pleiotrophin (PTN) also known as heparin-binding brain mitogen (HBBM) or heparin-binding growth factor 8 (HBGF-8) or neurite growth-promoting factor 1 (NEGF1) or heparin affinity regulatory peptide (HARP) or heparin binding growth associated molecule (HB-GAM) is a protein that in humans is encoded by the PTN gene. Pleiotrophin is an 18-kDa growth factor that has a high affinity for heparin. It is structurally related to midkine and retinoic acid induced heparin-binding protein.
Nuclear respiratory factor 1, also known as Nrf1, Nrf-1, NRF1 and NRF-1, encodes a protein that homodimerizes and functions as a transcription factor which activates the expression of some key metabolic genes regulating cellular growth and nuclear genes required for respiration, heme biosynthesis, and mitochondrial DNA transcription and replication. The protein has also been associated with the regulation of neurite outgrowth. Alternate transcriptional splice variants, which encode the same protein, have been characterized. Additional variants encoding different protein isoforms have been described but they have not been fully characterized. Confusion has occurred in bibliographic databases due to the shared symbol of NRF1 for this gene and for "nuclear factor -like 1" which has an official symbol of NFE2L1.
Disintegrin and metalloproteinase domain-containing protein 12 is an enzyme that in humans is encoded by the ADAM12 gene. ADAM12 has two splice variants: ADAM12-L, the long form, has a transmembrane region and ADAM12-S, a shorter variant, is soluble and lacks the transmembrane and cytoplasmic domains.
Hypoxia-inducible factor 3 alpha is a protein that in humans is encoded by the HIF3A gene.
Retinoic acid-induced protein 3 is a protein that in humans is encoded by the GPRC5A gene. This gene and its encoded mRNA was first identified as a phorbol ester-induced gene, and named Phorbol Ester Induced Gen 1 (PEIG-1); two years later it was rediscovered as a retinoic acid-inducible gene, and named Retinoic Acid-Inducible Gene 1 (RAIG1). Its encoded protein was later named Retinoic acid-induced protein 3.
PYCARD, often referred to as ASC, is a protein that in humans is encoded by the PYCARD gene. It is localized mainly in the nucleus of monocytes and macrophages. In case of pathogen infection, however, it relocalizes rapidly to the cytoplasm, perinuclear space, endoplasmic reticulum and mitochondria and it is a key adaptor protein in activation of the inflammasome.
Egl nine homolog 2 is a protein that in humans is encoded by the EGLN2 gene. ELGN2 is an alpha-ketoglutarate-dependent hydroxylase, a superfamily of non-haem iron-containing proteins.
Hypoxia-inducible factor prolyl hydroxylase 2 (HIF-PH2), or prolyl hydroxylase domain-containing protein 2 (PHD2), is an enzyme encoded by the EGLN1 gene. It is also known as Egl nine homolog 1. PHD2 is a α-ketoglutarate/2-oxoglutarate-dependent hydroxylase, a superfamily non-haem iron-containing proteins. In humans, PHD2 is one of the three isoforms of hypoxia-inducible factor-proline dioxygenase, which is also known as HIF prolyl-hydroxylase.
Sterile alpha motif and leucine zipper containing kinase AZK, also known as ZAK, is a human gene.
Heat shock factor protein 2 is a protein that in humans is encoded by the HSF2 gene.
Hypoxia-inducible factor 1-alpha inhibitor is a protein that in humans is encoded by the HIF1AN gene.
TSC22 domain family protein 1 is a protein that in humans is encoded by the TSC22D1 gene.
Prolyl 4-hydroxylase subunit alpha-1 is an enzyme that in humans is encoded by the P4HA1 gene.
CAMP responsive element binding protein-like 1, also known as CREBL1, is a protein which in humans is encoded by the CREBL1 gene.
Prolyl 4-hydroxylase subunit alpha-2 is an enzyme that in humans is encoded by the P4HA2 gene.
Disintegrin and metalloproteinase domain-containing protein 28 is an enzyme that in humans is encoded by the ADAM28 gene.
Semaphorin-4C is a protein that in humans is encoded by the SEMA4C gene.
Zinc finger protein PLAGL2 is a protein that in humans is encoded by the PLAGL2 gene.
Hypoxia-inducible factor-asparagine dioxygenase (EC 1.14.11.30, HIF hydroxylase) is an enzyme with systematic name hypoxia-inducible factor-L-asparagine, 2-oxoglutarate:oxygen oxidoreductase (4-hydroxylating). This enzyme catalyses the following chemical reaction:
hypoxia-inducible factor-L-asparagine + 2-oxoglutarate + O2 hypoxia-inducible factor-(3S)-3-hydroxy-L-asparagine + succinate + CO2
Alpha-ketoglutarate-dependent hydroxylases are a major class of non-heme iron proteins that catalyse a wide range of reactions. These reactions include hydroxylation reactions, demethylations, ring expansions, ring closures, and desaturations. Functionally, the αKG-dependent hydroxylases are comparable to cytochrome P450 enzymes. Both use O2 and reducing equivalents as cosubstrates and both generate water.
