Activity summary

Cofilin-1 also known just as cofilin is a small actin-modulating protein with a molecular weight of approximately 19 kDa. It is part of the actin chemical structure regulation and plays an important role in actin filament dynamics by severing and depolymerizing actin filaments. Cofilin-1 expresses widely in both muscle and non-muscle tissues modulating the actin cytoskeleton which is critical for cell movement shape and various signaling pathways. The phosphorylated form of this protein known as phospho-cofilin or p-cofilin is another significant state to consider.

Biological function summary

Through its interaction with actin filaments cofilin-1 functions to regulate the length and turnover of the actin cytoskeleton within cells. Cofilin-1 is part of a critical complex where it binds to actin monomers and filaments to facilitate the disassembly and recycling of actin. This regulation impacts cellular activities such as migration endocytosis and division influencing how cells respond to internal and external signals. Cofilin-1's ability to bind and sever actin filaments forms an important part of its functional mechanism altering the cytoskeletal architecture for various cellular processes.

Pathways

Cofilin-1 participates principally in the actin dynamics component of the cytoskeleton remodeling pathway. Within this framework cofilin-1 acts alongside other proteins like actin-depolymerizing factor (ADF) and tropomyosin influencing assembly and disassembly cycles of actin filaments. The Rho family of GTPases regulates cofilin-1 activity through signaling pathways such as the Rho/ROCK/LIMK pathway. This signaling regulation affects actin filament organization impacting cellular processes like axonal guidance and directed cell movement.

Associated diseases and disorders

There is a strong connection between cofilin-1 dysregulation and neurodegenerative diseases such as Alzheimer's disease and certain types of cancer. In Alzheimer's disease cofilin-1 activity influenced by abnormal cofilin phosphorylation forms part of the pathological mechanisms that lead to synaptic dysfunction and neurofibrillary tangles. In the context of cancer cofilin-1 collaborates with proteins such as RhoA and LIM kinase contributing to cancer cell invasion and metastasis by reorganizing the actin cytoskeleton to facilitate cell motility. Understanding these interactions helps in targeting therapeutic strategies against these conditions.
