Human ICMT adenoviral particles

The isoprenylcysteine carboxyl methyltransferase (ICMT) gene encodes a key enzyme involved in the post-translational modification of proteins, particularly those containing a C-terminal isoprenylcysteine residue. ICMT catalyzes the carboxyl methylation of these residues, a process that is essential for the proper localization and function of many proteins, including small GTPases such as members of the Ras and Rho families. These proteins play key roles in cellular signaling pathways that regulate proliferation, differentiation, and survival. Dysregulation of ICMT activity has been implicated in a variety of diseases, including cancer and neurodegenerative disorders, making it an important target for therapeutic research.

Human ICMT adenoviral particles are genetically engineered viral vectors designed to deliver the ICMT gene or its variants into mammalian cells for functional studies or therapeutic applications. These particles are based on adenovirus serotype 5 (Ad5) and have been engineered to ensure efficient transduction while minimizing immunogenicity. The adenoviral backbone is replication-defective, enhancing safety for both in vitro and in vivo experiments. These particles are ideal for studying the biological roles of ICMT, including its effects on protein prenylation, membrane localization, and downstream signaling cascades. In addition, they can serve as a tool for gene therapy studies, especially in diseases associated with ICMT dysfunction.
