Protein Structure
|
|
Function |
May mediate accelerated ATP-independent bidirectional transbilayer migration of phospholipids upon binding calcium ions that results in a loss of phospholipid asymmetry in the plasma membrane. May play a central role in the initiation of fibrin clot formation, in the activation of mast cells and in the recognition of apoptotic and injured cells by the reticuloendothelial system. {ECO:0000269PubMed:12010804}.May play a role in the antiviral response of interferon (IFN) by amplifying and enhancing the IFN response through increased expression of select subset of potent antiviral genes. May contribute to cytokine-regulated cell proliferation and differentiation. {ECO:0000269PubMed:12010804}.

Subcellular Localization |
Membrane {ECO:0000250}; Single-pass type II membrane protein. Membrane; Lipid-anchor {ECO:0000250}; Cytoplasmic side. Nucleus {ECO:0000250}.
|
Disease Associations |
Note=Participates in a chromosomal translocation that produces MMTRA1A which is leukemogenic to syngenic SL mice and athymic nude mice.
|
Tissue Specificity |
Highly expressed in kidney, lung, liver and bone marrow, slightly in spleen, heart and macrophage.
