Inner membrane complex of Plasmodium (IMC (for "inner membrane complex"))

The **inner membrane complex (IMC)** is a specialized organelle found in *Plasmodium* species and other apicomplexan parasites. It is a system of flattened cisternal membranes located just beneath the parasite plasma membrane. The IMC plays an essential role in maintaining the shape and mechanical stability of the parasite, particularly during its invasive stages such as merozoites and gametocytes[2][4][9]. It also serves as a scaffold for cytoskeletal elements like microtubules, which are crucial for cell elongation, division, motility, and successful invasion or egress from host cells[3][5]. The molecular composition includes numerous proteins—some regulated by post-translational modifications such as palmitoylation—that anchor them to this structure[3][5]. **"Plasmodium membrane integrity"** is not itself a canonical molecular target but rather describes an important biological property or process involving multiple components—primarily the IMC but also including other associated proteins and complexes that maintain or regulate this integrity[1][7]. Disruption of key components involved in maintaining this integrity can impair parasite development or survival; for example, knockdown of PfCullin-2 disrupts both cell division and proper formation/maintenance of internal membranes[1][7]. Because "Plasmodium membrane integrity" refers to a functional property rather than a discrete molecule or receptor—and encompasses several structures/proteins—it should not be considered a single therapeutic target. Instead, individual proteins within these systems (such as PfCRL4 ubiquitin ligase components or specific IMC proteins) may serve as valid drug targets. **Summary judgment:** This entry ("Plasmodium membrane integrity") is too broad/vague to be considered a canonical molecular target; it refers instead to an emergent property maintained by multiple molecules/complexes within *Plasmodium* parasites. For structured data purposes you should map references about "membrane integrity" to more specific entities like "Inner membrane complex protein 1g," "PfCRL4," etc., when possible[1][5][7].
