    SUBCELLULAR LOCALIZATION     intracellular
  • nuclear matrix
  • interaction with PIAS4 redistributes it from the cytoplasm to the nucleus
  • basic FUNCTION
  • key regulator of RB1 gene expression
  • functions as a regulatory node to couple two important signaling pathways to regulate cell growth and survival during mouse embryogenesis
  • enhancing the transcriptional activation of the p21 promoter by PIAS4 whereas PIAS4 transcription activity is severely reduced upon RB1CC1 depletion by RNA interference
  • tumor suppressor implicated in the regulation of RB1 (retinoblastoma 1) expression
  • autophagy factor that functions together with ULK1 and ULK2
  • crucial signaling component to coordinately regulate different cellular events by its interaction with multiple signaling pathways
  • playing a role in the regulation of neuronal homeostasis through its function in autophagy
  • may play a role in homeostasis of neurons
  • key intrinsic regulator of fetal hematopoietic stem cells (HSCs) and implicate a potential role for autophagy in the maintenance of fetal hematopoiesis and HSCs
  • essentially requires binding with SMARCB1, a chromatin-remodeling factor) to activate the CDKN2A promoter, in order to enhance the RB1 pathway and acts as a tumor suppressor
  • new function in the regulation of DNA damage response and cell survival through its activity in autophagy
  • with ATG13, act in concert during autophagy induction
  • caused suppression of type II collagen synthesis in the differentiated chondrocytes through multimodal signaling involving Erk suppression and NFKB activation
  • role for RB1CC1 in tumor suppression in the presence of APC dysfunction
  • essential for autophagy induction in mammalian cells, resulting in a progressive loss of neural stem cells
  • RB1CC1-mediated autophagy contributes to the maintenance and functions of neural stem cells through regulation of oxidative state
    a component
  • part of ULK1-ATG13-RB1CC1 autophagy regulatory complex
    small molecule
  • PIAS4-interacting protein (interaction depends on the integrity of the RING finger of PIAS4 and the C-terminus of RB1CC1)
  • binding to the GC-rich region of the RB1 promoter
  • activates the expression of CDKN2A through the activation of its promoter
  • RB1CC1/FIP200 is a novel positive regulator of TGFB signaling that functions as a substrate-selective cofactor of RNF111
  • TP53 regulates autophagy through a direct molecular interaction with RB1CC1, a protein that is essential for the very apical step of autophagy initiation
  • ATG13 function is strictly depends on RB1CC1 binding, and has an additional function independent of ULK1/2 (with RB1CC1, act in concert during autophagy induction) (
  • interacts with the oncoprotein CTNNB1
  • interaction between RB1CC1 and ATG16L1, essential components of the ULK1 and ATG5 complexes, respectively
  • RFWD2 modulates RB1CC1-associated activities, which may contribute to a variety of cellular functions that RFWD2 is involved in

    deletion in hematopoietic cells leads to perinatal lethality and severe anemia
    tumoral   deletion
