HOMOLOGY

FAMILY	melanoma antigen, family A
	cancer testis antigen (CTA) family

CATEGORY

antigen

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm
	intracellular,nucleus
text	identified in the nucleus and cytoplasm of spermatogonia and in primary spermatocytes but not in spermatids or Sertoli cells (Takahashi 1995)

basic FUNCTION	directing expression of antigen MZ2-E
	normal tissue antigen compartmmentalized in particular testicular cells playing an important role in the early phase of the spermatogenesis (Takahashi 1995)
	may play a role in embryonal development and tumor transformation or aspects of tumor progression
	inhibiting the activity of a SKIP-interacting transactivator
	can act as a potent transcriptional repressor
	participating in the setting of specific gene expression patterns for tumor cell growth or spermatogenesis
	with CTAG1B, are associated with highly proliferating germ cells (Gjerstorff 2007)
	MAGEA1 functions as a co-factor of TRIM31 ubiquitin-ligase
	MAGEA1, MAGEA2, MAGEA3, MAGEA5, MAGEA8 genes are crucial in maintaining normal testicular size and protecting germ cells from excessive apoptosis under genotoxic stress

INTERACTION

DNA

RNA

small molecule

protein	binding to SKIP and by recruiting HDACs, MAGE-A1 can act as a potent transcriptional repressor
	DNA methylation has a dominant role in the epigenetic hierarchy governing MAGEA1 expression
	CTCFL and Sp1 have opposite effects on the regulation of MAGEA1 gene expression
	MAGEA1 interaction stimulates TRIM31 ubiquitin-ligase activity
	MAGEA1 reduced intracellular segment of NOTCH1 receptor (NICD1) stability by promoting the ubiquitin modification of NICD1, and interacted with FBXW7, subunit of E3 ubiquitin protein ligase complex SCF, and the latter was functionally involved in NICD1 ubiquitination and degradation
	interaction between MAGEA1 and CTCF, which is required for the binding of MAGEA1 to the CTCFL promoter and is critical for the recruitment of DNMT3A
	MAGEA1 inhibits the expression of CTCL via increased promoter methylation
	MIRLET7A1 functions as a tumor suppressor by targeting MAGEA1 in breast cancer
