Function of microglia-specific calcium binding protein, Iba-1

Expression and Distribution of Calcium-Binding Protein S100P in Human Placenta during Pregnancy

Regulation of myocardial function by histidine-rich, calcium-binding protein.

Impaired sarcoplasmic reticulum (SR) Ca release has been suggested to contribute to the depressed cardiac function in heart failure. The release of Ca from the SR may be regulated by the ryanodine receptor, triadin, junctin, calsequestrin, and a histidine-rich, Ca-binding protein (HRC). We observed that the levels of HRC were reduced in animal models and human heart failure. To gain insight int...

A novel biomarker associated with distress in humans: calcium-binding protein, spermatid-specific 1 (CABS1).

Calcium-binding protein spermatid-specific 1 (CABS1) is expressed in the human submandibular gland and has an anti-inflammatory motif similar to that in submandibular rat 1 in rats. Here, we investigate CABS1 in human saliva and its association with psychological and physiological distress and inflammation in humans. Volunteers participated across three studies: 1) weekly baseline measures; 2) ...

Calcium binding properties of recombinant calcium binding protein 40, a major calcium binding protein of lower eukaryote Physarum polycephalum.

Calcium binding protein 40 (CBP40) is a Ca(2+)-binding protein abundant in the plasmodia of Physarum polycephalum. CBP40 consists four EF-hand domains in the COOH-terminal half and a putative alpha-helix domain in the NH(2)-terminal half. We expressed recombinant proteins of CBP40 in Escherichia coli to investigate its Ca(2+)-binding properties. Recombinant proteins of CBP40 bound 4 mol of Ca(2...

Microglia of medicinal leech (Hirudo medicinalis) express a specific activation marker homologous to vertebrate ionized calcium-binding adapter molecule 1 (Iba1/alias aif-1).

The Ionized calcium-Binding Adapter molecule 1 (Iba1), also known as Allograft Inflammatory Factor 1 (AIF-1), is a 17 kDa cytokine-inducible protein, produced by activated macrophages during chronic transplant rejection and inflammatory reactions in Vertebrates. In mammalian central nervous system (CNS), Iba1 is a sensitive marker associated with activated macrophages/microglia and is upregulat...
