Human S100 Calcium Binding Protein A1 (S100A1) interaction partners

1. Data suggest that TRPM4 exhibits binding sites for calmodulin (CaM) and S100 calcium-binding protein A1 (S100A1) located in very distal part of TRPM4 N-terminus. (TRPM4 = transient receptor potential cation channel subfamily M member 4)

2. Data found that S100A1 was upregulated in hepatocellular carcinoma (HCC) tissues, and its upregulation was associated with large tumor size, low differentiation, and shorter survival rates. Further results supports the hypothesis that S100A1 functions as an oncogene and may be a biomarker for the prognosis of patients with HCC. S100A1 exerted its oncogenic function by interacting with LATS1 and activating Hippo pathway.

3. The results indicate that changes in the circulating level of S100A1 protein occur in metabolic syndrome patients. The strong correlation between serum zinc-alpha2-glycoprotein and S100A1 might suggest that production or release of these two proteins could be related mechanistically.

8. a molecular mechanism for the potential regulation of TRPM1 by S100A1

9. Data suggest that calcium signaling plays important role in prevention of protein misfolding; complexes of S100A1 and STIP1 are key players in this pathway; the stoichiometry of S100A1/STIP1 interaction appears to be three S100A1 dimers plus one STIP1 monomer; each S100A1-STIP1-binding interaction is entropically driven. (S100A1 = S100 calcium binding protein A1; STIP1 = stress-induced-phosphoprotein 1) [REVIEW]

10. Data suggest that three dimers of S100A1 (S100 calcium binding protein A1) associate with one molecule of STIP1 (stress-inducible phosphoprotein 1) in a calcium-dependent manner; individual STIP1 TPR (tetratricopeptide repeat) domains, TPR1, TPR2A and TPR2B, bind a single S100A1 dimer with significantly different affinities; TPR2B domain possesses highest affinity for S100A1.

11. Results identified amino acids motif in S100A1 for protein binding to 2-oxohistidine which appears to be an evolutionarily conserved capacity from bacteria to human.

13. CaM and S100A1 can concurrently bind to and functionally modulate RyR1 and RyR2, but this does not involve direct competition at the RyR CaM binding site.

14. In line with these observations, rhesus monkey rhadinovirus infection resulted in rapid degradation of SP100, followed by degradation of PML and the loss of ND10 structures, whereas the protein levels of ATRX and DAXX remained constant.

15. High Serum protein S100 levels are associated with postoperative delirium after off-pump coronary artery bypass surgery.

16. molecular dynamics simulations of S100A1 in the apo/holo (Ca(2+)-free/bound) states, is reported.

17. The relationship between the degree of infiltration by S100-positive (S100+) dendritic cells and prognostic factors, including histological subtype, histological grade, peritumor inflammatory infiltration, and stromal desmoplasia, were examined.

18. In this review, we aim to describe the molecular basis and regulatory function of S100A1--{REVIEW}

19. Data indicate that Cu-oxidized S100 calcium binding protein A4 (S100A4) interacted with S100 calcium binding protein A1 (S100A1) and prevented protein phosphatase 5 (PP5) activation.

20. Patients with acute myocardial infarction (MI) showed significantly increased S100A1 serum levels. S100A1 signaling in cardiac fibroblasts occurs through endosomal TLR4/MyD88.

Cow (Bovine) S100 Calcium Binding Protein A1 (S100A1) interaction partners

1. identified S100A1, but not calmodulin or other S100 proteins, as a potent molecular chaperone and a new member of the Hsp70/Hsp90 multichaperone complex (S100A1)

2. Results suggest that S100A1 can act as a linker between the calcium and redox signalling pathways.

3. beta-mercaptoethanol modification of apo-S100A1 makes its structure more similar to that of holo-S100A1, so that it becomes much better adjusted for calcium coordination.

Mouse (Murine) S100 Calcium Binding Protein A1 (S100A1) interaction partners

1. Data (including data from studies using knockout mice) suggest that S100A1 (S-100 calcium-binding protein A1, alpha chain) is involved in protein kinase A- (RIIalpha and RIIbeta)-dependent signaling resulting in nuclear redistribution/influx of HDAC4 (histone deacetylase 4) in skeletal muscle fibers.

2. S100A1-KO exhibited increased right ventricular (RV) weight and elevated RV pressure in the absence of altered left ventricular filling pressures, increase in wall thickness of muscularized pulmonary arteries and a reduction in microvascular perfusion.

4. S100A1 ablationalso reduced plaque associated and increased non-plaque associated PO4-Akt and PO4-GSK3beta staining.

5. Patients with acute myocardial infarction (MI) showed significantly increased S100A1 serum levels. Experimental MI in mice induced comparable S100A1 release. S100A1 signaling in cardiac fibroblasts occurs through endosomal TLR4/MyD88.

7. Report downregulation of S100A1 expression in critical limb ischemia impairs postischemic angiogenesis via compromised proangiogenic endothelial cell function and nitric oxide synthase regulation.

8. S100A1 and calmodulin bind to an overlapping domain on the ryanodine receptor type 1 to tune the Ca2+ release process, and thereby regulate skeletal muscle function. (Review)

9. The RyR1-L3625D mutation removed both an early activating effect of S100A1 and calmodulin and delayed the suppression of RyR1 Ca2+ release, providing new insights into calmodulin and S100A1 regulation of skeletal muscle excitation-contraction coupling.

10. Data suggest that the absence of S100A1 suppresses physiological AP-induced Ca(2+) release flux, resulting in impaired contractile activation and force production in skeletal muscle.

11. Chronic absence of S100A1 results in enhanced L-type Ca2+ channel activity combined with a blunted sarcoplasmic reticulum Ca2+ release amplification.
