Ca/CaMKs

Our company offers many products related to Ca/CaMKs for your research needs.

Lysophospholipid Receptors

Sigma-Aldrich offers many products related to lysophospholipid receptors for your research needs.

Glycine Receptors

The amino acid glycine is a major inhibitory neurotransmitter in the vertebrate CNS. Glycinergic synapses are particularly abundant in spinal cord and brain stem, but are also found in higher brain regions including the hippocampus. The inhibitory actions of glycine

Growth Factors and Cytokines: Classification and Nomenclature

Growth factors and cytokines have historically been classified into ‘families’ based on their apparent activity and/or impact on a given cell type, system, or tissue.

Spectrin

Spectrin is the major component of the protein network, which covers the cytoplasmic surface of vertebrate, erythrocyte membranes. It is a high molecular weight heterodimer, composed of two subunits (molecular weights of approximately 230 kDa and 250 kDa)

Glycosphingolipids

Adenylyl Cyclase

Adenylyl cyclases occur throughout the animal kingdom and play diverse roles in cell regulation. In bacteria, the enzyme may be regulated in response to nutrients or it may constitute a toxic factor in mammals, as with adenylyl cyclases of B.

P2 Receptors: P2X Ion Channel Family

We offer many products related to P2X ion channel family receptors for your research needs.

Actinin

Introduction about α-Actinin protein present in both muscle and non-muscle cells.

Troponin

Troponin together with tropomyosin, regulate the binding of myosin to actin. Troponin is a trimeric protein composed of Troponin subunits I, C and T. Troponin C binds calcium ions, Troponin T binds to tropomyosin and troponin I binds

Characteristic Metabolites for Inborn Errors of Amino Acid Metabolism

Inborn errors of metabolism are caused by changes in specific enzymatic reactions and hundreds of different such alterations, which affect about 1 of every 5000 newborns, have been characterized.

Cyclin-dependent Kinases (CDKs)

Cyclin dependent kinases (CDKs) are typical serine/threonine kinases that display the 11 subdomains shared by all kinases. The complete sequence of the Homo sapiens genome shows that among the ~30,000 predicted genes, there are 13 CDKs and 25 cyclins. Eleven

Leukotriene Receptors

We offers many products related to GRKs for your research needs.

EGFR

Our company offers many products related to EGFR for your research needs.

PDGFR

Sigma-Aldrich offers many products related to PDGFR for your research needs.

Phosphoprotein Phosphatases (Tyrosine)

Protein tyrosine phosphatases (PTPs) and related enzymes (more than a hundred coded by the human genome) are more numerous than serine/threonine phosphatases. They belong to four families, three of which possess a conserved cysteine for catalysis and some conserved features

Potassium Channels

We offer many products related to potassium channels for your research needs.

Cannabinoid Receptors

We offer many products related to cannabinoid receptors for your research needs.

Cholesterol Esterification

Cholesterol undergoes esterification to improve transport. Cholesterol esters are more easily packaged into the interior of lipoproteins - increasing the quantity that can be readily transported in the blood stream.

Phospholipase C

The hydrolysis of a minor membrane phospholipid, phosphatidylinositol 4,5-bisphosphate (PIP2) by a specific phospholipase C (PLC) is one of the earliest key events in the regulation of various cell functions by more than 100 extracellular signaling molecules.

FGFR

We offer many products related to FGFR for your research needs.

Vasoactive Intestinal Peptide Receptors

We offer many products related to vasoactive intestinal peptide receptors for your research needs.

Glutamate Receptors (Ion Channel Family)

Glycogen Synthase Kinase 3 (GSK-3) Overview

We offers many products related to GSK-3 for your research needs.

Peptidoglycan Structure, Biosynthesis and Function

The basic structure of peptidoglycan (PGN) contains a carbohydrate backbone of alternating units of N-acetylglucosamine (GlcNAc) and Nacetylmuramic acid, with the N-acetylmuramic acid residues cross-linked to peptides.
