Protein

Twinfilin-1

Gene

Twf1

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Actin-binding protein involved in motile and morphological processes. Inhibits actin polymerization, likely by sequestering G-actin. By capping the barbed ends of filaments, it also regulates motility. Seems to play an important role in clathrin-mediated endocytosis and distribution of endocytic organelles.4 Publications

Expressioni

Tissue specificityi

Widely expressed with highest levels in brain, liver and kidney. Also expressed in heart, lung and testis. Not detected in spleen or skeletal muscle.3 Publications

Developmental stagei

Expression was widespread throughout the embryonic stages analyzed; E10.5, E12.5, E14.5 and E18.5. At E14.5, strongest expression was observed in the developing central and peripheral nervous system (CNS and PNS, respectively) and in the olfactory sensory epithelium. In the CNS, the proliferating neuronal precursors in the ventricular zone expressed it more than the postmitotic neurons. At E18.5, highest expression levels were detected in the mechanosensory hair cells of the inner ear and in the differentiated keratinocytes of the skin.1 Publication

Interactioni

Subunit structurei

Interacts with G-actin; ADP-actin form and capping protein (CP). May also be able to interact with TWF2 and phosphoinositides, PI(4,5)P2. When bound to PI(4,5)P2, it is down-regulated.4 Publications
