background:
S100 beta is a member of the S100 family of proteins containing 2 EF-hand calcium binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21; however, this gene is located at 21q22.3. This protein may function in neurite extension, proliferation of melanoma cells, stimulation of Ca2+ fluxes, inhibition of PKC mediated phosphorylation, astrocytosis and axonal proliferation, and inhibition of microtubule assembly. Chromosomal rearrangements and altered expression of this gene have been implicated in several neurological, neoplastic, and other types of diseases, including Alzheimer's disease, Down's syndrome, epilepsy, amyotrophic lateral sclerosis, melanoma, and type I diabetes.
Function:
Weakly binds calcium but binds zinc very tightly-distinct binding sites with different affinities exist for both ions on each monomer. Physiological concentrations of potassium ion antagonize the binding of both divalent cations, especially affecting high-affinity calcium-binding sites. Binds to and initiates the activation of STK38 by releasing autoinhibitory intramolecular interactions within the kinase. Interaction with AGER after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling.
Subunit:
Dimer of either two alpha chains, or two beta chains, or one alpha and one beta chain. The S100B dimer binds two molecules of STK38 (By similarity). The S100B dimer interacts with two molecules of CAPZA1.
Subcellular Location:
Cytoplasm. Nucleus.
Tissue Specificity:
Although predominant among the water-soluble brain proteins, S100 is also found in a variety of other tissues.
Similarity:
Belongs to the S-101 family.
Contains 2 EF-hand domains.

結(jié)構(gòu)蛋白（Structural Proteins）
S100B是一組可溶性、相對低分子質(zhì)量、高酸性蛋白，屬神經(jīng)膠質(zhì)細胞特異性蛋白，亦可存在于神經(jīng)纖維中。在研究腸神經(jīng)系統(tǒng)的形態(tài)特征及結(jié)構(gòu)特征中，S100B有良好的表達功能。
S100B蛋白其生理作用尚不清楚，可能與細胞內(nèi)鈣離子媒介的調(diào)節(jié)作用有關(guān)。S100B蛋白可存在于神經(jīng)鞘瘤，成軟骨細胞瘤、軟骨肉瘤、骨肉瘤、神經(jīng)膠質(zhì)瘤、郎格罕斯細胞瘤、一些癌腫和黑素細胞腫瘤等。
在免疫組化中，除了惡性黑素瘤皮損，S100B蛋白還在良性黑素細胞痣中增加，如：藍痣、普通后天痣、雀斑樣痣、Spitz痣、氣球狀細胞痣、色素性梭形細胞痣和發(fā)育不良痣中表達。還有報道S100B蛋白的染色強度與腫瘤細胞的黑素含量呈負相關(guān)。結(jié)締組織增生性的或親神經(jīng)的黑素瘤不易染色。
