Web5 jun. 2009 · MITF is a gene with at least 6 alternate transcripts expressed in different tissues (Amae et al. 1998). All isoforms are identical from exons 2–5 and 6–9. MITF-M, contained in melanocyte lineage–specific cells, has an alternatively spliced exon 6A that consists of an insertion of 6 amino acids, ACIFPT (Amae et al. 1998; Yasumoto et al. 1998). WebMITF is a basic helix-loop-helix (hHLH)-leucine zipper protein that plays a role in the development of various cell types, including neural crest-derived melanocytes and optic cup-derived retinal pigment epithelial cells ( Fuse et al., 1999 ).

MITF in melanoma: mechanisms behind its expression and activity
Webprotein levels of pre-existing MITF-M over the course of minutes, and then up-regulated the expression of MITF-M de novo with maximal amount of protein at 4 h and mRNA at 2 h in B16-F0 cells (Figure 1A, upper). To clarify the fate of pre-existing MITF-M in response to SCF/KIT, de novo protein synthesis was inhibited WebMITF, which binds to the M-box sequence (AGTCATGTG CT) located in the tyrosinase distal elements (TDEs) after its activation (22). Since the promoter region of MITF contains the consensus CRE sequence, the expression of MITF can also be increased by α-MSH stimulation in a cAMP-dependent manner (23). This demonstrated that the α-MSH-MC1R start up recovery sober living

Web13 jan. 2024 · The microphthalmia-associated transcription factor (MITF) is a critical regulator of melanocyte development and differentiation. It also plays an important role in melanoma where it has been described as a molecular rheostat that, depending on activity levels, allows reversible switching between different cellular states.
