Ribonuclease 3 commonly known as Eosinophil Cationic Protein (ECP) is an enzyme with ribonuclease activity. Researchers sometimes refer to it as human RNase 3. The protein has a molecular mass of about 18 to 22 kDa and is highly expressed in eosinophils a type of white blood cell primarily involved in allergic responses and parasitic infections. ECP exhibits cytotoxic bactericidal and antiviral activities contributing to its diverse biological functions.
Biological function summary
Ribonuclease 3 plays a significant role in immune defense mechanisms leveraging its arginine-rich domain to interact with negatively charged microbial surfaces. This interaction allows ECP to participate in the destruction of pathogen cell walls. It is not part of a larger complex but interacts with cellular membranes making it an effective tool against a variety of pathogens. Whether acting through enzymatic activity or by disrupting membrane integrity ECP maintains a pivotal role in host defense.
Pathways
ECP influences processes in both innate and adaptive immune responses. It actively participates in the Th2 cell-mediated immune response which is critical for countering parasitic infections. This protein connects with other components like major basic protein and eosinophil peroxidase through these pathways forming an integrated network that boosts immune responses. Its presence in pathways linked to inflammation and immunity highlights its multifunctionality and importance.
ECP levels correlate with conditions such as asthma and eosinophilic esophagitis. In asthma elevated ECP levels indicate eosinophilic inflammation and airway hyperresponsiveness. Researchers have identified a connection between ECP and proteins like interleukin-5 which modulate eosinophil activity. Similarly in eosinophilic esophagitis increased ECP levels indicate ongoing inflammation and tissue damage providing insights into disease progression and severity.
