Integrin is a heterodimer consisting of two transmembrane glycoprotein subunits (α and β),which are covalently bound.T/F

Statement Analysis

1. Identifying the Statement: The statement claims that integrin is a heterodimer made up of two transmembrane glycoprotein subunits (α and β) that are covalently bound.

2. Understanding Integrins: Integrins are indeed heterodimeric proteins consisting of two different subunits, which can be either alpha (α) or beta (β). They span the cell membrane and play a crucial role in cell adhesion, signaling, and interactions with the extracellular matrix.

3. Subunit Binding: While integrins are heterodimers, the interaction between α and β subunits is typically non-covalent. This means that while they are bound together to form a functional integrin, this binding does not involve covalent bonds.

Final Answer

The statement is False. Integrins are heterodimers composed of α and β subunits that are non-covalently bound, not covalently bound.
