HEBP2 heme binding protein 2 [Homo sapiens (human)] - Gene

Summary

Official Symbol: HEBP2provided by HGNC
Official Full Name: heme binding protein 2provided by HGNC
Primary source: HGNC:HGNC:15716
See related: Ensembl:ENSG00000051620 MIM:605825; AllianceGenome:HGNC:15716
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: PP23; SOUL; C6orf34; C6ORF34B
Summary: The protein encoded by this gene is found predominately in the cytoplasm, where it plays a role in the collapse of mitochondrial membrane potential (MMP) prior to necrotic cell death. The encoded protein enhances outer and inner mitochondrial membrane permeabilization, especially under conditions of oxidative stress. [provided by RefSeq, May 2016]

What's a GeneRIF?

The gene copy numbers and mRNA levels for both ALG-2 and HEBP2 are significantly upregulated in breast and lung cancer. Coexpression of ALG-2 and HEBP2 markedly increases the cytoplasmic pool of ALG-2 and alters the subcellular distribution of HEBP2. Abnormalities in the ALG-2/HEBP2 interaction impairs spindle orientation and positioning during mitosis.
Title: Deregulated ALG-2/HEBP2 axis alters microtubule dynamics and mitotic spindle behavior to stimulate cancer development.
There are important structural differences in the BH3 domain in the intact SOUL molecule and the same sequence bound to Bcl-xL.
Title: Structural changes in the BH3 domain of SOUL protein upon interaction with the anti-apoptotic protein Bcl-xL.
SOUL can be a novel member of the BH3 domain-only proteins that cannot induce cell death alone but can facilitate both outer and inner mitochondrial membrane permeabilization and predominantly necrotic cell death in oxidative stress.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
