MAM domain containing glycosylphosphatidylinositol anchor 1

This gene encodes a glycosylphosphatidylinositol (GPI)-anchored cell surface glycoprotein that is expressed predominantly in the developing nervous system. In addition to possessing several cell adhesion molecule-like domains, the mature protein has six Ig-like domains, a single fibronectin type III domain, a MAM domain and a C-terminal GPI-anchoring site. Studies in other mammals suggest this protein plays a role in cell adhesion, migration, and axon guidance and, in the developing brain, neuronal migration. In humans, this gene is associated with bipolar disorder and schizophrenia. [provided by RefSeq, Oct 2016]

MAM domain containing glycosylphosphatidylinositol anchor 2

Predicted to be involved in regulation of synapse organization and spinal cord motor neuron differentiation. Predicted to act upstream of or within several processes, including motor behavior; negative regulation of neuron apoptotic process; and neuron migration. Predicted to be located in extracellular region and plasma membrane. Predicted to be active in GABA-ergic synapse; glutamatergic synapse; and postsynaptic density membrane.

MAM domain containing 2 pseudogene

MAM and LDL receptor class A domain containing 1

This gene encodes a conserved protein that features multiple MAM (meprin-A5-protein tyrosine phosphatase mu) and LDLR A2 (low density lipoprotein receptor A2) domains. Expression of this gene is enriched in the small intestine and is upregulated during differentiation of a human cell line that exhibits properties of intestinal epithelial cells. The encoded protein has been shown to modulate production of FGF19 in a human intestinal cell line and may regulate bile acid metabolism in the liver. A synergistic interaction between an allele of this gene and the APOE E4 allele is associated with an elevated risk of Alzheimer's disease in human patients. [provided by RefSeq, Jul 2017]
