SIRP beta 1 Protein, Human (HEK293, hFc)
SIRP beta 1 protein negatively regulates receptor tyrosine kinase signaling and recruits SYK for myeloid cell activation. It interacts with TYROBP as a homodimer, facilitating SYK recruitment. This intricate molecular interplay is crucial for modulating myeloid cell activation and regulating cellular signaling. SIRP beta 1 occupies a central position in protein interactions that contribute to its functional role. SIRP beta 1 Protein, Human (HEK293, hFc) is the recombinant human-derived SIRP beta 1 protein, expressed by HEK293, with C-hFc labeled tag.
- Species: Human
- Source: HEK293

Description
SIRP beta 1 protein negatively regulates receptor tyrosine kinase signaling and recruits SYK for myeloid cell activation. It interacts with TYROBP as a homodimer, facilitating SYK recruitment. This intricate molecular interplay is crucial for modulating myeloid cell activation and regulating cellular signaling. SIRP beta 1 occupies a central position in protein interactions that contribute to its functional role. SIRP beta 1 Protein, Human (HEK293, hFc) is the recombinant human-derived SIRP beta 1 protein, expressed by HEK293, with C-hFc labeled tag.
Background
SIRP beta 1 protein, an immunoglobulin-like cell surface receptor, plays a vital role in the negative regulation of receptor tyrosine kinase-coupled signaling processes. Additionally, it participates in the recruitment of the tyrosine kinase SYK, triggering the activation of myeloid cells when associated with TYROBP. Existing as a homodimer with disulfide linkages, SIRP beta 1 interacts specifically with TYROBP, leading to the recruitment of SYK. This intricate molecular interplay positions SIRP beta 1 at the nexus of cellular signaling regulation, highlighting its significance in modulating myeloid cell activation and the intricate network of protein interactions that contribute to its functional role.

Product Properties
Lyophilized powder.
<1 EU/μg, determined by LAL method.
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).
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.
Room temperature in continental US; may vary elsewhere.
