MSP2

MSP2 is an acronym that refers to several concepts across different fields. The most well-documented usage is in malaria research, where MSP-2 stands for merozoite surface protein 2, a protein expressed on the surface of Plasmodium falciparum merozoites. The MSP2 gene is known as msp2. This protein is highly polymorphic, with two principal allelic families, FC27 and 3D7. Because of its variability, MSP-2 is used as a molecular marker in studies of parasite diversity and in assessments of malaria vaccines and diagnostic tools.

In information technology and related industries, MSP2 is sometimes used as a label for a second-generation managed services platform or as a version identifier within product lines. The meaning of MSP2 in these contexts varies by organization and is not standardized. The term is therefore highly context-dependent, and readers should consult domain-specific documentation to determine the intended meaning in a given setting.
