Although neither ARID1A nor ARID1B were identified as MITF-interacting proteins in melanoma cells, this does not preclude the possibility that ARID1A and/or ARID1B are involved in differentiation through interactions with other transcription factors, such as SOX10 and TFAP2A, which collaborate with MITF, or potentially other transcription factors that independently promote differentiation. This evidence concerns the gene SOX10 and melanoma.
