Recombinant Human Malignant fibrous histiocytoma-amplified sequence 1 (MFHAS1), Truncated

Uniprot Id

Q9Y4C4

Target Species

Human

Target Name

MFHAS1

Target Full Name

Malignant fibrous histiocytoma-amplified sequence 1

Target Function

Probable GTP-binding protein. Functions in innate immunity and more specifically the inflammatory response as a regulator of the Toll-like receptor TLR2 and TLR4 signaling pathways. Negatively regulates the part of the TLR4 signaling pathway that leads to the activation of the transcription factor AP-1. By retaining the phosphatase complex PP2A into the cytoplasm, prevents the dephosphorylation of the AP-1 subunit JUN which is required for proper activation of the transcription factor. Both inhibits and activates the TLR2-dependent signaling pathway. Positively regulates the TLR2 signaling pathway to activate specifically the downstream p38 and JNK MAP kinases and promote the polarization of macrophages toward the pro-inflammatory M1 phenotype. It may also play a role in the regulation of inflammation induced by high glucose through the PKB/AKT signaling pathway. Also involved in erythrocyte differentiation through activation of the ERK1/ERK2 signaling pathway

Target Involvement

A chromosomal aberration involving MFHAS1 may be a cause of B-cell lymphoma. Translocation t(8;14)(p23.1;q21) with a cryptic exon named '14q21 element'. The resulting fusion protein named 'chimeric MASL1' is tumorigenic in nude mice.

Target Subcellular Location

Cytoplasm.

Target Tissue Specificity

Ubiquitously expressed. Overexpressed in malignant fibrous histiocytomas. Expressed in red blood cells (at protein level).
