ARID1B and melanoma: 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.
