Semaphorin-4D/SEMA4D Protein, Rat (HEK293, His)

Semaphorin-4D (SEMA4D) is predicted to participate in the same protein binding, signaling receptor binding, and transmembrane signaling receptor activities. Its multiple roles, including negative regulation of osteoblast differentiation and modulation of neuronal projection development, highlight its functional versatility. Semaphorin-4D/SEMA4D Protein, Rat (HEK293, His) is the recombinant rat-derived Semaphorin-4D/SEMA4D protein, expressed by HEK293 , with C-His labeled tag. The total length of Semaphorin-4D/SEMA4D Protein, Rat (HEK293, His) is 712 a.a., with molecular weight of ~96-115 kDa.

Semaphorin-4D (SEMA4D) is predicted to possess identical protein binding activity, signaling receptor binding activity, and transmembrane signaling receptor activity. Its involvement in various processes, including negative regulation of osteoblast differentiation, regulation of neuron projection development, and regulation of phosphate metabolic processes, underscores its diverse functions. SEMA4D is anticipated to act upstream of or within the positive regulation of axonogenesis, suggesting a role in neuronal development. The predicted activity in the extracellular space and its status as an integral component of the plasma membrane further emphasize its potential significance in intercellular communication. With biased expression observed in tissues such as the spleen, thymus, and nine other tissues, SEMA4D's intricate involvement in cellular processes and its potential impact on tissue-specific functions become areas of interest for further exploration.

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. 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.
