IL-20R alpha Protein, Human (HEK293, His)

IL-20R alpha Protein (IL20RA) is the alpha subunit of IL-20 receptor, forms functional heterodimers with different subunit protein and involves in STAT3 activation pathway. The IL20RA/IL20RB dimer is a receptor for IL-19, IL-20 and IL-24, while the IL20RA/IL10RB dimer is a receptor for IL-26. IL-20R alpha Protein is consists of 553 amino acids (M1-N553) with a transmembrane domain (251-271 a.a.). IL-20R alpha Protein, Human (HEK293, His) is produced in HEK293 cells with a C-Terminal His-tag.

제품 설명

IL-20R alpha Protein (IL20RA) is the alpha subunit of IL-20 receptor, forms functional heterodimers with different subunit protein and involves in STAT3 activation pathway[1]. The IL20RA/IL20RB dimer is a receptor for IL-19, IL-20 and IL-24, while the IL20RA/IL10RB dimer is a receptor for IL-26[3]. IL-20R alpha Protein is consists of 553 amino acids (M1-N553) with a transmembrane domain (251-271 a.a.). IL-20R alpha Protein, Human (HEK293, His) is produced in HEK293 cells with a C-Terminal His-tag.

Background

IL-20R alpha, also known as a alpha subunit of IL-20 receptor (IL-20RA), belongs to the type II cytokine receptor family[1].
IL-20R alpha is widely expressed with highest levels in skin and testis and high levels in brain[2].
IL20RA and IL20RB is found to be upregulated in psoriatic skin lesions on keratinocytes[3].
IL-20R alpha forms functional heterodimers with different subunit protein. IL-20R alpha serves as the receptor for IL-19, IL-20 and IL-24 by dimerizing with IL20RB, however serves as the receptor for IL-26 by dimerizing with IL-10RB. IL-20R alpha transduces ligand-binding at least in part through STAT3 activation, and plays an important role in epidermal function and psoriasis[4].
The sequence of amino acids in IL-12 beta proteins of human is very different from mouse (64.64%).

In Vitro

IL-20 receptor mRNA is decreased in psoriasis, and shows high protein level in mononuclear leukocytes in the papillary dermis and along the dermoepidermal junction[4].

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
