Multisensorisina

Multisensorisina is a proposed class of intracellular transduction proteins characterized by the ability to sense and integrate information from multiple sensory modalities, including optical, chemical, and mechanical cues, and to convert these into coordinated intracellular responses. The concept aims to describe proteins that act as hubs for multimodal sensory information within a single molecular framework.

The name combines “multisensor” with the common protein suffix “-ina” used in theoretical nomenclature. The idea has circulated in discussions of cellular signaling and sensory biology as a possible mechanism to explain rapid, context-dependent cellular decisions in organisms that rely on multiple sensory inputs.

The proposed architecture is modular, with distinct input domains that can bind light, ligands, or mechanical stimuli, connected by flexible linkers to a central signaling module. Activation is hypothesized to involve allosteric communication among domains, enabling a single protein to integrate signals and trigger downstream pathways, such as calcium signaling, kinase activity, or transcriptional responses.

If real, multisensorisina would be expected to localize to sensory epithelia, neural membranes, or other signaling hubs where multimodal information is processed. Proposed functions include rapid behavioral decisions, homeostatic regulation, and adaptive responses to complex environmental cues.

As of now, multisensorisina remains a speculative concept with limited empirical support. Researchers emphasize the need for structural characterization, genetic evidence, and functional assays to establish its existence and biological relevance. The term is discussed in theoretical or exploratory contexts and should be treated as a hypothesis rather than a defined protein family.
