TAGLN3 (Transgelin-3) is a member of the transgelin family of actin-binding proteins, which play critical roles in regulating cytoskeletal dynamics, cell motility, and contractility. Structurally, it contains a conserved calponin-like homology (CH) domain that mediates interactions with actin filaments, influencing cell shape and mechanical properties. Unlike its isoforms TAGLN (Transgelin-1), predominantly expressed in smooth muscle cells, and TAGLN2. found in immune and endothelial cells, TAGLN3 shows tissue-specific enrichment in the nervous system, skeletal muscle, and heart, suggesting distinct functional roles in these tissues.
Recombinant TAGLN3 protein is engineered for in vitro studies to explore its molecular mechanisms and pathophysiological relevance. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), it enables biochemical assays, structural studies, and interaction analyses. Research highlights its involvement in neuronal development, synaptic plasticity, and muscle function. Dysregulation of TAGLN3 has been implicated in neurological disorders, cardiovascular diseases, and cancer progression, where altered cytoskeletal organization contributes to pathological phenotypes such as metastasis or impaired contractility.
Despite advancements, challenges remain in elucidating post-translational modifications (e.g., phosphorylation) that modulate TAGLN3 activity. Its role in signal transduction pathways, particularly in cross-talk with Rho GTPases or integrins, is an active area of investigation. Recombinant TAGLN3 also serves as a tool for antibody development and high-throughput drug screening, offering potential therapeutic avenues. However, functional redundancy within the transgelin family and context-dependent expression patterns complicate mechanistic studies, necessitating tissue-specific models. Ongoing research aims to clarify its dual roles in physiological maintenance and disease, bridging gaps in understanding cytoskeletal regulation.
