Corneumiin

Corneumiin is a term that has appeared chiefly in speculative discussions and fictional contexts to denote a hypothetical protein associated with the stratum corneum, the outermost layer of the skin. The name combines corneum, the Latin word for horn, with the common protein-name suffix -iin, a pattern sometimes used in fictional or provisional biology.

In these imagined or hypothetical frameworks, corneumiin is described as a small, possibly secreted or membrane‑associated peptide that could influence keratin filament organization, lipid lamella formation, and barrier function through interactions with keratinocytes, ceramides, or other components of the cornified envelope. Such descriptions are speculative and illustrate how a single molecular player might contribute to skin barrier properties.

There is no scientific evidence supporting the existence of corneumiin. It has not been identified in peer‑reviewed biochemical or dermatological research, and there are no published sequences, structures, or functional assays in reputable databases. Consequently, corneumiin is generally treated as a fictional construct or a placeholder term used for teaching, thought experiments, or fictional narratives rather than a validated biological entity.

If corneumiin appears in non-fictional material, readers should seek confirmation from primary sources or peer‑reviewed literature. In practice, reliable information about skin barrier biology continues to rely on established components such as the stratum corneum, keratin, filaggrin, loricrin, and ceramides.
