CC -!- FUNCTION: Transcription factor that binds DNA in a non-specific manner,
CC yet also specifically recognizes the core sequence 5'-CAC[GA]TG-3'.
CC Activates the transcription of growth-related genes. Binds to the VEGFA
CC promoter, promoting VEGFA production and subsequent sprouting
CC angiogenesis. Regulator of somatic reprogramming, controls self-renewal
CC of embryonic stem cells. Functions with TAF6L to activate target gene
CC expression through RNA polymerase II pause release (By similarity).
CC Positively regulates transcription of HNRNPA1, HNRNPA2 and PTBP1 which
CC in turn regulate splicing of pyruvate kinase PKM by binding
CC repressively to sequences flanking PKM exon 9, inhibiting exon 9
CC inclusion and resulting in exon 10 inclusion and production of the PKM
CC M2 isoform (By similarity). {ECO:0000250|UniProtKB:P01106,
CC ECO:0000250|UniProtKB:P01108}.
CC -!- SUBUNIT: Efficient DNA binding requires dimerization with another bHLH
CC protein. Binds DNA as a heterodimer with MAX (By similarity). Interacts
CC with TAF1C and SPAG9. Interacts with PARP10. Interacts with KDM5A and
CC KDM5B. Interacts (when phosphorylated at Thr-58 and Ser-62) with FBXW7.
CC Interacts with PIM2. Interacts with RIOX1. The heterodimer MYC:MAX
CC interacts with ABI1; the interaction may enhance MYC:MAX
CC transcriptional activity. Interacts with TRIM6 (By similarity).
CC Interacts with NPM1; the binary complex is recruited to the promoter of
CC MYC target genes and enhances their transcription (By similarity).
CC Interacts with CIP2A; leading to the stabilization of MYC (By
CC similarity). {ECO:0000250|UniProtKB:P01106,
CC ECO:0000250|UniProtKB:P01108}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleoplasm
CC {ECO:0000250|UniProtKB:P01106}. Nucleus, nucleolus
CC {ECO:0000250|UniProtKB:P01106}.
CC -!- DOMAIN: The 9aaTAD motif is a transactivation domain present in a large
CC number of yeast and animal transcription factors.
CC {ECO:0000250|UniProtKB:P01106}.
CC -!- PTM: Phosphorylated by PRKDC (By similarity). Phosphorylation at Ser-
CC 329 by PIM2 leads to the stabilization of MYC (By similarity).
CC Phosphorylation at Ser-62 by CDK2 prevents Ras-induced senescence.
CC Phosphorylated at Ser-62 by DYRK2; this primes the protein for
CC subsequent phosphorylation by GSK3B at Thr-58. Phosphorylation at Thr-
CC 58 and Ser-62 by GSK3 is required for ubiquitination and degradation by
CC the proteasome. Dephosphorylation at Ser-62 by protein phosphatase 2A
CC (PPP2CA) promotes its degradation; interaction with PPP2CA is enhanced
CC by AMBRA1 (By similarity). {ECO:0000250|UniProtKB:P01106,
CC ECO:0000250|UniProtKB:P01108}.
CC -!- PTM: Ubiquitinated by the SCF(FBXW7) complex when phosphorylated at
CC Thr-58 and Ser-62, leading to its degradation by the proteasome.
CC Ubiquitination is counteracted by USP28 in the nucleoplasm and USP36 in
CC the nucleolus, both interacting with of FBXW7, leading to its
CC deubiquitination and preventing degradation. Also polyubiquitinated by
CC the DCX(TRPC4AP) complex. Ubiquitinated by TRIM6 in a phosphorylation-
CC independent manner. {ECO:0000250|UniProtKB:P01106,
CC ECO:0000250|UniProtKB:P01108}.
