Anti-ALIX antibody [3A9]

Supplementary info

Activity summary

ALIX also known as PDCD6IP or ALIX G is an adapter protein involved in various cellular processes. It holds a molecular weight of approximately 95-100 kDa and is widely expressed in different tissue types including HEK 293 cells. ALIX plays a significant role as a component of the endosomal sorting complexes required for transport (ESCRT) machinery contributing to membrane dynamics and intracellular trafficking.

Biological function summary

ALIX acts as an important mediator in the regulation of cellular membrane remodeling. It associates with several protein complexes influencing the budding and fission of vesicles and endosomes. The protein also interacts with ubiquitin and other factors guiding protein sorting and maintaining cellular homeostasis. This adapter characteristic makes ALIX essential for recycling receptors and maintaining cell surface receptor expression levels.

Pathways

ALIX is involved in the ESCRT pathway and the apoptotic pathways. It works closely with proteins like TSG101 and CHMP4 to facilitate vesicle formation and dispatch impacting cellular processes like signaling and waste disposal. Furthermore ALIX regulates apoptosis by interacting with proteins such as ALG-2 and to some extent with apoptosis-related membranes to mediate programmed cell death.

Associated diseases and disorders

ALIX has established links to cancer progression and neurodegenerative disorders. Its participation in membrane remodeling and protein sorting correlates with tumor development with evidence showing that altered expression affects oncogenic pathways. Additionally dysregulation of ALIX-associated pathways has implications in neurodegenerative diseases where ALIX and proteins such as those in the ESCRT complex could play a role in the degradation of misfolded proteins and endocytic dysfunctions contributing to disease pathology.
