HOMOLOGY

interspecies

homolog to murine Tmeff1

Homologene

FAMILY

tomoregulin family

CATEGORY

tumor suppressor

SUBCELLULAR LOCALIZATION	plasma membrane
text	expressed on the cell membrane
	predominantly redistributed to the endoplasmic reticulum (ER) when coexpressed with addicsin (ARL6IP5)

basic FUNCTION	potential role for TMEFF1 in growth factor signaling (
	may behave as a tumor suppressor gene in brain cancers
	inhibits NODAL signaling through direct binding to the nodal coreceptor Cripto
	having different activities depending on the presence of the cytoplasmic tail and its anchorage to the membrane
	TMEFF1 and TMEFF2 could be playing similar roles in different tissues and/or developmental stages
	is a growth factor that is primarily involved in embryonic development and adult central nervous system (CNS) function
	is a carcinogenic gene in ovarian cancer and can be regulated by TP53 transcription
	involved in the physiological functions of the central nervous system, embryonic development, and other biological processes
	acts as a tumor-promoting gene in ovarian cancer

INTERACTION

DNA

RNA

small molecule

protein	binds to the NODAL coreceptor CRIPTO, but does not associate with either NODAL or the type I ALK (activin receptor-like kinase) 4 receptor
	tomoregulin-1 (TMEFF1) is a novel addicsin (ARL6IP5)-associated factor
	ARL6IP5 in the ER controls intracellular TMEFF1 trafficking from the ER to plasma membrane and regulates cell migration through its interaction with TMEFF1

Therapy target
	System Type Disorder Pubmed cancer reproductive ovary may be considered as a potential therapeutic target for ovarian cancer cardiovascular cardiomyopathy   could be a therapeutic target to control the development of cardiac hypertrophy cancer reproductive ovary the interaction between AHNAK and TMEFF1 may become a potential anti-tumor target for ovarian cancer treatment

ANIMAL & CELL MODELS

	plays a protective role in the modulation of adverse cardiac remodeling from pressure overload in mice
	high Tgfb1 doses increased tomoregulin-1 (Tmeff1) levels, resulting in the repression of Bmp2 and bone formation in mice
