Overview
Properties
This protein was expressed as an N-terminal His-tag fusion protein using Escherichia coli, and purified using Immobilized Metal Ion Affinity Chromatography. In some cases, smaller protein fragments may be present in addition to the intended expression product as a result of premature termination during translation in E. coli and subsequent co-purification via the His-tag. In some cases purified proteins run at a molecular weight different to the theoretically calculated molecular weight. This may be as a result of unequally distributed charges in the amino acid sequence. Alternatively, dimerisation of the expression product can occur under oxygen limitation during expression/cultivation.

Defects in SDHB are the cause of hereditary paragangliomas type 4 (PGL4) [MIM:115310]; also known as familial non-chromaffin paragangliomas type 4. Paragangliomas refer to rare and mostly benign tumors that arise from any component of the neuroendocrine system. PGL4 is characterized by the development of mostly benign, highly vascular, slow growing tumors in the head and neck. In the head and neck region, the carotid body is the largest of all paraganglia and is also the most common site of the tumors.
Defects in SDHB are a cause of paraganglioma and gastric stromal sarcoma (PGGSS) [MIM:606864]; also called Carney-Stratakis syndrome. Gastrointestinal stromal tumors may be sporadic or inherited in an autosomal dominant manner, alone or as a component of a syndrome associated with other tumors, such as in the context of neurofibromatosis type 1 (NF1). Patients have both gastrointestinal stromal tumors and paragangliomas. Susceptibility to the tumors was inherited in an apparently autosomal dominant manner, with incomplete penetrance.
Defects in SDHB are a cause of Cowden-like syndrome (CWDLS) [MIM:612359]. Cowden-like syndrome is a cancer predisposition syndrome associated with elevated risk for tumors of the breast, thyroid, kidney and uterus.
