Insights

The calcium- and integrin-binding protein (CIB) family, including CIB2 and CIB3, is crucial for hearing and balance. These proteins also play roles in various diseases, highlighting their broad biological significance.

Area of Science:

  • Molecular Biology
  • Genetics
  • Physiology

Background:

  • The calcium- and integrin-binding protein (CIB) family consists of four conserved members (CIB1-4).
  • CIB proteins possess canonical EF-hand motifs, suggesting calcium-dependent functions.
  • Their roles in the inner ear are under investigation, with specific importance noted for auditory and balance functions.

Purpose of the Study:

  • To review the conserved structure and diverse biological functions of the CIB protein family.
  • To summarize the distribution and specific roles of CIB proteins, particularly in sensory organs.
  • To emphasize the critical involvement of CIB2 and CIB3 in hearing and balance.

Main Methods:

  • Literature review of studies on CIB family proteins.
  • Analysis of conserved structural features (EF-hand motifs).
  • Summary of functional data from various biological contexts.

Main Results:

  • CIB family members share conserved structures and calcium-binding capabilities.
  • CIB2 is essential for auditory function, while CIB2 and CIB3 jointly regulate balance.
  • CIB proteins are implicated in the pathogenesis of neurological disorders, cardiovascular diseases, cancer, and male infertility.

Conclusions:

  • The CIB family exhibits significant multifunctionality beyond sensory roles.
  • CIB2 and CIB3 are key regulators of hearing and balance, respectively.
  • Understanding CIB protein functions is vital for insights into various diseases.

Integrins01:10

Integrins

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...

Activation of Integrins01:15

Activation of Integrins

Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Cell Adhesion Molecules - Types and Functions

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
