Cell adhesion is a multi-step process initiated by receptor binding to extracellular matrix (ECM) components. This triggers intracellular signaling cascades leading to spreading and organization of the cytoskeleton with focal adhesions. Essential cellular processes such as locomotion, gene expression and survival are regulated by both signaling and mechanical forces generated by the organized Cited by: 3.

One known function of cell surface calreticulin is its involvement in focal adhesion disassembly. Thrombospondin (TSP) interacts with cell surface calreticulin and signals through low density lipoprotein receptor-related protein (LRP) to promote focal adhesion disassembly and cell migration [29,30].Cited by:   It has been shown that calreticulin associates with the cytoplasmic domains of integrin α-subunits and that this interaction can influence integrin-mediated cell adhesion to extracellular matrix4,5.

expression and matrix deposition, leading to differences in cell spreading and focal adhesion formation in cells differentially expressing calreticulin.

We further show that these effects of calreticulin occur via a c-Src-regulated pathway and that c-Src activity is inversely related to calreticulin abundance. Since. Through calcium regulation and other mechanisms, calreticulin is thought to play a role in the control of gene activity, cell growth and division (proliferation) and movement (migration), the attachment of cells to one another (adhesion), and regulation of programmed cell death (apoptosis).

Although it was originally characterized as a Ca 2+-binding protein, calreticulin and its recently identified cell surface isoform ectocalreticulin have emerged as regulators of integrin-mediated Ca 2+ signaling and cell adhesion (Coppolino et al., ;Coppolino and.

Within the ER, calreticulin also plays an important role in calcium homeostasis. Calreticulin has also been identified outside of the ER and plays unique roles in each subcellular compartment.

On the cell surface, calreticulin interacts with thrombospondin (TSP) to promote disassembly of focal adhesion complexes and cellular migration (2). calreticulin: (kal-re-tik'yū-lin), Intracellular calcium-binding protein, with cell adhesion and vascular regulatory actions; found in the endoplasmic reticulum.

Please note the number of articles fluctuates since newly identified citations are added and citations for discontinued. Calcium is a universal signaling molecule involved in many cellular functions such as cell motility, metabolism, protein modification, protein folding, and apoptosis.

Calcium is stored in the endoplasmic reticulum (ER), where it is buffered by calcium binding chaperones such as calnexin and calreticulin, and is released via the IP 3 Receptor Category: Primary Antibodies. As such, calreticulin presumably does not alter protein folding but regulates proper timing for efficient folding and subunit assembly.

Furthermore, calreticulin retains proteins in non-native conformation within the ER and targets them for degradation (2,3). Groenendyk, J.
