A member of the SNF2 family of chromatin remodeling proteins, Lymphoid-specific helicase (HELLS, also known as Lsh) assumes various roles in normal development, survival, de novo or maintenance DNA methylation, gene silencing, and heterochromatin formation and organization. It is shown to serve as cancer progression marker in conjunction with CEP55 and FOXM1 for the detection of head and neck squamous cell carcinoma. It is also reported that expression of Lsh is crucial for meiotic progression in mouse spermatocytes. Lsh is shown to directly associate with the 5' DMR of the Cdkn1c promoter, and thereby regulate its gene expression. Additionally, Lsh is reported as a regulator of repressive chromatin at retrotransposons, and is demonstrated to mediate the silencing of stem cell-specific genes such as Oct4.
