SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus,nucleoplasm
	intracellular,nucleus,chromatin/chromosome
text	perinucleolar structures

basic FUNCTION	inhibiting DNA synthesis
	inhibiting oncogenic transformation
	playing a role in the expression of genes required for the G1/S transition
	can inhibit cell proliferation independent of the pocket proteins
	LIN9 and MYBL2 were both required for transcription of G(2)/M genes such as CCCNB1 and Survivin
	role of LIN9 in development and mitotic gene regulation, suggesting that it may function as a haploinsufficient tumor suppressor
	depletion of LIN9 results in downregulation of mitotic genes and in upregulation of differentiation-specific genes
	is essential for proliferation and genome stability of ESCs by activating genes with important functions in mitosis and cytokinesis

CELLULAR PROCESS	cell cycle
	nucleotide, replication

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

LIN9 and the pocket proteins RBL1 and RBL2 are members of the DREAM complex that in G0 represses cell cycle genes

INTERACTION

DNA

RNA

small molecule

protein	interacting with RB1
	KIA1456 and tRNA modifications are linked to inhibition of tumour growth via LIN9 and HIF1A-dependent mechanisms
