该基因编码一种参与tlr4信号通路的支架蛋白，该蛋白可能刺激细胞因子的产生和内皮细胞的迁移，以应对入侵的病原体。编码蛋白也被认为是一种潜在的肿瘤抑制因子，可能对肿瘤细胞的增殖、凋亡和侵袭产生负调控作用，在多种人类癌症中已观察到该基因的表达减少该基因突变可能与人类患者的异常皮肤色素沉着有关[由RefSeq提供，2016年10月]
This gene encodes a scaffold protein involved in the TLR4 signaling pathway that may stimulate cytokine production and endothelial cell migration in response to invading pathogens. The encoded protein has also been described as a potential tumor suppressor that may negatively regulate proliferation, apoptosis, and invasion of cancer cells, and reduced expression of this gene has been observed in multiple human cancers. Mutations in this gene may be associated with abnormal skin pigmentation in human patients. [provided by RefSeq, Oct 2016]
