RAB45 Recombinant Rabbit Monoclonal Antibody [JE65-33]

Ras and EF-hand domain-containing protein also known as Ras-related protein Rab-45 is a protein that in humans is encoded by the RASEF gene. RASEF intervenes in a direct manner in biological processes such as protein transport and small GTPase mediated signal transduction. Its molecular functions include GTP binding and calcium ion binding. The guanine-nucleotide forms of the Rab domain regulate the protein's localization. RASEF is mainly found in the perinuclear region of the cell. In addition, the protein's mid-region also seems to be involved in the perinuclear localization. This could be due to its interaction with membrane compartments. This induces a huge diversity of biochemical intracellular cascades which, in addition to some other reactions, influence cell behaviour. When these growth factors are altered, the signal cytoplasmatic circuits can not function properly, which could provoke serious pathologies like cancer. The constitutively active form of Ras oncoprotein is expressed in high levels in bladder carcinomas, leukemias, colon, breast, lung and skin cancers. Some researchers have discovered that Ras and Ef-hand domain containing proteins are commonly overexpressed in primary lung cancers and its intervention is crucial for the proliferation and survival of cancerous cells. There is ongoing research that is studying the possibility of using RASEF as a clinically promising prognostic biomarker and therapeutic target for lung cancer. Some recent studies have revealed the viability of using RASEF as a target for this disease.
