Summary: Predicted to enable RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including negative regulation of cell cycle; negative regulation of vulval development; and positive regulation of brood size. Located in nucleus. Is expressed in several structures, including head and tail. Used to study intellectual disability. Human ortholog(s) of this gene implicated in several diseases, including high grade glioma (multiple); osteosarcoma; prostate cancer; retinoblastoma (multiple); and small cell carcinoma. Orthologous to several human genes including RBL1 (RB transcriptional corepressor like 1) and RBL2 (RB transcriptional corepressor like 2). [provided by Alliance of Genome Resources, Dec 2024]

Study reports that LIN-35 indeed mediates the association of E2F-DP and MuvB, a function that stabilizes (Dp/Retinoblastoma(Rb)-like/E2F/MuvB) or DREAM transcriptional repressor complex subunit occupancy at target genes. In the absence of LIN-35, the occupancy of E2F-DP and MuvB at most DREAM target genes decreases dramatically and many of those genes become upregulated.
