Nipsnap homolog 2 (NIPSNAP2)

Nipsnap homolog 2 (NIPSNAP2, also known as GBAS or glioblastoma amplified sequence) is a member of the NipSnap protein family and is encoded by the GBAS gene on chromosome 7p12. NIPSNAP2 is localized primarily to mitochondria, where it participates in maintaining mitochondrial health, most notably through facilitating the selective autophagic clearance of damaged mitochondria (mitophagy) by recruiting core autophagy machinery and "eat me" signals. It interacts with proteins involved in vesicular transport, and its expression is highest in skeletal muscle and heart tissue. The region containing the GBAS gene is amplified in a significant proportion of glioblastoma cases, suggesting a potential role in cancer, although it is not currently an established therapeutic target. NIPSNAP2 is implicated in cellular processes such as metabolism and oxidative phosphorylation, and may play a role in neurodegenerative diseases including Parkinson’s disease by modulating mitochondrial quality control systems[1][2][3][5][7].
