Summary: Predicted to enable RNA polymerase II transcription regulatory region sequence-specific DNA binding activity and promoter-specific chromatin binding activity. Acts upstream of or within negative regulation of transcription by RNA polymerase II. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including genitourinary system; hemolymphoid system gland; palatal shelf; retina; and telencephalon. Used to study retinoblastoma and urinary bladder cancer. Orthologous to human RBL1 (RB transcriptional corepressor like 1). [provided by Alliance of Genome Resources, Dec 2024]

p107 is relevant for the metabolic activity of both brown and white adipocytes under conditions of leanness and obesity, and its deficiency is associated with increased thermogenesis and browning of WAT and hence stimulation of energy expenditure.
Title: p107 Deficiency Increases Energy Expenditure by Inducing Brown-Fat Thermogenesis and Browning of White Adipose Tissue.
Results show that ablation of the three members of the retinoblastoma family (RB1, p107 and p130) which targets a variety of adult lung epithelial cells, leads to spontaneous velopment of tumorlets, benign precancerous neuroendocrine (NE) lesions that do not progress to malignant tumors. Data imply the requirement of other oncogenic signaling pathways for full transformation in NE lung lesions mutant for the Rb family.

the transcriptional corepressor p107 orchestrates a metabolic checkpoint that determines adipocyte lineage fates for non-committed progenitors.

Findings indicate that inactivation of the Rb family proteins (Rb, p107, and p130) in hematopoietic stem cells (HSCs) progressively impairs their homeostasis, which is rescued upon repression of suppressor of cytokine signaling 3 protein (Socs3) expression in triple knockout (TKO) HSCs.

p107 is required for the efficient recruitment of an activating SWI/SNF chromatin-remodeling complex, an essential event in Alpl induction.

while p107 alone did not have an essential role in islet homeostasis, when combined with Rb deletion, its absence potentiated apoptosis of both alpha and beta cells resulting in glucose intolerance and diminished islet mass with ageing
Title: Rb and p107 are required for alpha cell survival, beta cell cycle control and glucagon-like peptide-1 action.
Findings indicate that retinoblastoma-like protein p107 expression in stem cells commits cells to the white versus brown adipose lineage.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
