Abstract
Background
Calcium-binding proteins are heterogeneous proteins that act binding this ion in specific domains, performing numerous functions.
Objective
In the present review, we aim to gather principal information about S100B protein in the Central Nervous System (CNS), highlighting its particularities, mapping, functionalities, and consequences on CNS dysfunction.
Methods
The research was carried out by searching Pubmed, Medline, Science Direct, Lilacs, the Cochrane Library, and Web of Science databases using the following descriptors: S100 protein; Central Nervous System; Nervous Lesions, as well as their corresponding terms in Portuguese and Spanish. The terms were first searched separately, then together.
Results
Due to its ability to bind with calcium, S100B is involved in the regulation of several intra- and extracellular physiological processes. As well as being multifunctional, this protein can be considered both a “marker” and “signaling” since it is capable of triggering functions of detection of and protection in situations of injury to the CNS.
Conclusions
In-depth studies are necessary to discover the innumerable actions of this protein which are still unknown. It is expected that these can bring varied benefits by elucidating its therapeutic potential in preclinical and clinical situations.
