SOX12（SRY-box transcription factor 12）属于SOX基因家族，该家族以共同的SRY（性别决定区Y）相关HMG（高迁移率族）盒DNA结合域为特征，能够调控胚胎发育、细胞命运决定和组织分化。SOX12在多种组织中广泛表达，但研究较少，已知其功能部分冗余于家族成员SOX4和SOX11。它通过结合DNA调控靶基因转录，参与神经发育、骨骼形成及造血过程。SOX12的突变可能破坏其DNA结合能力或转录调控功能，但目前与明确疾病的关联较少，少数研究提示其可能与某些癌症（如胶质瘤、乳腺癌）的进展相关，但证据有限。若SOX12过表达，可能异常激活下游促增殖或抗凋亡基因，促进肿瘤发生；而表达降低可能影响发育相关通路，但具体机制尚不清晰。SOX基因家族的共性包括：依赖HMG盒识别特定DNA序列（如AACAAT模体），通过与其他转录因子（如TCF/LEF）协作调控Wnt等信号通路，并在干细胞多能性、神经嵴细胞迁移等过程中发挥关键作用。目前SOX12的病理机制研究较少，需更多实验验证其功能及临床意义。
Members of the SOX family of transcription factors are characterized by the presence of a DNA-binding high mobility group (HMG) domain, homologous to the HMG box of sex-determining region Y (SRY). Forming a subgroup of the HMG domain superfamily, SOX proteins have been implicated in cell fate decisions in a diverse range of developmental processes. SOX transcription factors have diverse tissue-specific expression patterns during early development and have been proposed to act as target-specific transcription factors and/or as chromatin structure regulatory elements. The protein encoded by this gene was identified as a SOX family member based on conserved domains, and its expression in various tissues suggests a role in both differentiation and maintenance of several cell types.
