What's a GeneRIF?

MGARP overexpression caused both mitochondrial remodeling and cristae shaping, leading to the collapse of the mitochondrial network. The mitochondrial morphologies in MGARP-overexpressing cells were diverse; the cells became round or short, and their cristae were deformed and became discontinuous or circular.
Title: MGARP is ultrastructurally located in the inner faces of mitochondrial membranes.
The present study identified a proximal core sequence in the MGARP promoter that is composed of two enriched Sp1 binding motifs and established Sp1 as one major MGARP transactivator.
Title: Mitochondria-localized glutamic acid-rich protein (MGARP) gene transcription is regulated by Sp1.
Results identify a mitochondria-localized glutamic acid-rich protein (MGARP/OSAP) as one of the highly expressed proteins in retina.
Title: A mitochondria-localized glutamic acid-rich protein (MGARP/OSAP) is highly expressed in retina that exhibits a large area of intrinsic disorder.
Results identify a novel mitochondria protein, hypoxia up-regulated mitochondrial movement regulator (HUMMR), which is expressed in neurons and is markedly induced by hypoxia-inducible factor 1 alpha (HIF-1alpha).
Title: HUMMR, a hypoxia- and HIF-1alpha-inducible protein, alters mitochondrial distribution and transport.
OSAP is prominently expressed in steroidogenic tissues; results suggest that OSAP is involved in steroidogenesis, potentially through its ability to maintain mitochondrial abundance and morphology
Title: Expression of ovary-specific acidic protein in steroidogenic tissues: a possible role in steroidogenesis.

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.
