Structural Protein Function01:56

Structural Protein Function

29.9K
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to...

Protein and Protein Structure

87.4K
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

Mechanical Protein Functions01:58

Mechanical Protein Functions

5.6K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Fruit Development, Structure, and Function01:58

Fruit Development, Structure, and Function

25.2K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Toxicology

Background:

  • Snake venoms contain diverse proteins, including C-type lectin family members.
  • These include classical Ca2+-binding lectins and snake venom C-type lectin-related proteins (SV-CLRPs).
  • Both share the C-type lectin domain (CTLD) fold but differ in loop structures and assembly.

Purpose of the Study:

  • To explore the structural and functional versatility of SV-CLRPs.
  • To investigate their diverse molecular interactions and biological effects.
  • To highlight their potential as prototypes for medical diagnostics and therapeutics.

Main Methods:

  • Structural analysis of C-type lectin domain (CTLD) fold and loop variations.
  • Investigation of supramolecular complex assembly and stoichiometry.
  • Functional assays to determine inhibition or agonistic/antagonistic effects on target molecules and cellular receptors.

Main Results:

  • SV-CLRPs form versatile supramolecular complexes with varied subunit numbers and arrays.
  • They exhibit diverse abilities to inhibit, block, stimulate, or blunt cellular reactions by targeting molecules like coagulation factors and cell receptors.
  • Distinct interaction sites on SV-CLRPs mediate these varied effects.

Conclusions:

  • SV-CLRPs display remarkable versatility in targeting molecules involved in hemostasis, inflammation, and metastasis.
  • Their robust structure and high affinity for clinically relevant targets make them valuable.
  • Further elucidation of their molecular mechanisms is crucial for developing novel diagnostic and therapeutic tools.
