Target Details
| Target Function | Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. By binding to PIP2, it inhibits the formation of IP3 and DG. Inhibits androgen receptor (AR) and HTT aggregation and binding of G-actin is essential for its inhibition of AR. |
| Subcellular Location | Cytoplasm, cytoskeleton. |
| Protein Families | Profilin family |
| Database References | |
| Associated Diseases | Amyotrophic lateral sclerosis 18 (ALS18) |
| Tissue Specificity | Expressed in epididymis (at protein level). |
