AVL9 cell migration associated (AVL9)

Target
AVL9
Molecular classification
Other (conserved regulator of intracellular trafficking and late secretory pathway), Single-pass membrane protein
01

Overview

AVL9 cell migration associated (commonly known as AVL9) is a conserved, multifunctional protein involved in regulating intracellular trafficking, cell polarity, and exocytic transport—all processes essential for cell migration and tissue organization[2][3][4][6]. Located on recycling endosomes and functioning as a single-pass membrane protein, AVL9 is evolutionarily conserved from yeast to humans. In cancer biology, especially colorectal carcinoma, AVL9 upregulation promotes cell migration through the regulation of EGFR expression, making it a potential therapeutic target and biomarker for tumor aggressiveness and metastasis[1][2]. Beyond cancer, AVL9 is genetically linked to other processes such as myopia. Studies in model organisms highlight its critical roles in polarized secretion, Golgi function, and actin cytoskeleton organization, implying broader effects on cell and tissue biology[2][3]. Currently, no approved drugs target AVL9 directly, but its pathway can be manipulated by EGFR inhibitors in cancer treatment[1].

Mechanism of action

Not directly established; drugs like cetuximab act downstream by inhibiting EGFR, which AVL9 regulates in cancer cell migration

Biological functions

Cell migrationIntracellular traffickingCell polarityExocytic transportRegulation of EGFR expressionRegulation of cell–cell junctions

Disease associations

Cancer (especially colorectal carcinoma and lung adenocarcinoma)Potential role in myopia (genetic association)
05

Safety considerations

Not directly established; as AVL9 functions in cell migration and polarity, targeting it therapeutically could theoretically affect tissue organization and wound healing, but these effects are not reported in the literature
06

Interacting drugs

None directly established; EGFR inhibitors (e.g., cetuximab) can modulate AVL9’s pathway-mediated cell migration in cancers, but do not directly target AVL9
07

Biomarkers

High AVL9 expression is a potential biomarker for aggressive cancers, such as colorectal carcinoma and lung adenocarcinoma
