S100 Calcium-Binding Proteins and Ion Channels

open access: yesFrontiers in Pharmacology, 2012
S100 Ca2+-binding proteins have been associated with a multitude of intracellular Ca2+-mediated functions including regulation of the cell cycle, cell differentiation, cell motility and apoptosis, modulation of membrane-cytoskeletal interactions ...

Reviving lost binding sites: Exploring calcium‐binding site transitions between human and murine CD23

open access: yesFEBS Open Bio, 2021
Immunoglobulin E (IgE) is a central regulatory and triggering molecule of allergic immune responses. IgE’s interaction with CD23 modulates both IgE production and functional activities.CD23 is a noncanonical immunoglobulin receptor, unrelated to ...

Identification of CP12 as a Novel Calcium-Binding Protein in Chloroplasts

open access: yesPlants, 2013
Calcium plays an important role in the regulation of several chloroplast processes. However, very little is still understood about the calcium fluxes or calcium-binding proteins present in plastids.

An Update to Calcium Binding Proteins

open access: yes, 2019
Ca2+ binding proteins (CBP) are of key importance for calcium to play its role as a pivotal second messenger. CBP bind Ca2+ in specific domains, contributing to the regulation of its concentration at the cytosol and intracellular stores. They also participate in numerous cellular functions by acting as Ca2+ transporters across cell membranes or as Ca2+-

Calcium‐binding proteins in rat skin

open access: yesFEBS Letters, 1987
Skin Ca2+‐binding protein (SCaBP) was reported to be distinct from the Ca2+‐binding parvalbumin (PV), however, more recently its amino acid sequence was shown to be identical to PV. We purified a protein (Mr12 000; pI4.5) from isolated epidermis (free of other cell layers) of adult rats and whole skin (containing no PV) of newborn rats. This protein is

Calcium binding activity of the epidermal growth factor-like domains of the apicomplexan microneme protein EtMIC4

open access: yes, 2005
Microneme proteins are secreted from apicomplexan parasites during invasion of host cells and they play crucial roles in parasite-host cell adhesion.

Identification of Structural Calcium Binding Sites in Membrane-Bound Presenilin 1 and 2

open access: yes, 2020
Variants of presenilin (PS1 and PS2) are the main genetic risk factors of familial Alzheimer's disease and thus central to the disease etiology. Although mostly studied as catalytic units of γ-secretase controlling Aβ production, presenilins also affect ...

s-cyclophilin is retained intracellularly via a unique COOH-terminal sequence and colocalizes with the calcium storage protein calreticulin [PDF]

open access: yes, 1992
Cyclophilins (cyclosporin A-binding proteins) are conserved, ubiquitous, and abundant proteins that accelerate the isomerization of XaaPro peptide bonds and the refolding of proteins in vitro.

Comparison of VILIP-1 and VILIP-3 binding to phospholipid monolayers.

open access: yesPLoS ONE, 2014
The neuronal calcium sensor proteins Visinin-like Proteins 1 (VILIP-1) and 3 (VILIP-3) are effectors of guanylyl cyclase and acetyl choline receptors, and transduce calcium signals in the brain.

S100 Proteins—Intracellular and Extracellular Function in Norm and Pathology

open access: yesBiomolecules
The S100 proteins are small, ubiquitous, mostly homodimeric proteins containing two EF-hand structures, that is, helix-loop-helix motifs specialized in high-affinity calcium-binding (~10−6 M) [...]
