M2GAMMAGAMMA1

M2gammagamma1 is described in some educational and hypothetical datasets as a modular protein that would be encoded by the M2GAMMAGAMMA1 gene. It is characterized by two gamma-like domains connected by a short linker and is predicted to lack transmembrane segments, suggesting a soluble cytosolic or nucleoplasmic localization. Estimated molecular weight is around 25 kilodaltons, though exact figures may vary by isoform or species.

Discovery and gene context

The designation M2gammagamma1 has appeared in synthetic or teaching genomes intended to illustrate modular protein design. In these contexts, the gene is described as producing transcripts that generate one or more protein isoforms. Because the protein is not established in standard public databases, details about promoter structure, intron–exon organization, and regulatory elements are hypothetical and used for illustrative purposes.

Structure

Predicted architecture comprises two gamma-like domains in tandem, separated by a short flexible linker. The absence of predicted transmembrane regions implies a soluble protein that could engage in intermolecular interactions. The gamma-like domains are proposed to form globular folds, enabling potential binding to partner proteins or nucleic acids in silico.

Function and interactions

In speculative models, M2gammagamma1 is proposed to act as an adaptor or scaffold within signaling networks, potentially coordinating the assembly of multi-protein complexes. Interactions with other gamma-domain–containing proteins or with adaptor proteins associated with the hypothetical M2 receptor family have been proposed in teaching datasets, but there is no validated experimental evidence in real organisms.

Expression and localization

Hypothetical data suggest broad expression across tissues or cell types in the teaching genome, with cytosolic or nucleoplasmic localization. No confirmed imaging or proteomic data exist in real-world resources.

Evolution and notes

As a proposed construct, M2gammagamma1 lacks confirmed orthologs in public databases and is used primarily for conceptual demonstrations of domain architecture and protein-protein interactions. See also M2 receptor, gamma-domain proteins.
