CC -!- FUNCTION: Functions as a coactivator for aryl hydrocarbon and nuclear
CC receptors (NR). Recruited to promoters through its contact with the N-
CC terminal basic helix-loop-helix-Per-Arnt-Sim (PAS) domain of
CC transcription factors or coactivators, such as NCOA2. During ER-
CC activation acts synergistically in combination with other NCOA2-binding
CC proteins, such as EP300, CREBBP and CARM1. Involved in the
CC transcriptional activation of target genes in the Wnt/CTNNB1 pathway.
CC Functions as a secondary coactivator in LEF1-mediated transcriptional
CC activation via its interaction with CTNNB1. Coactivator function for
CC nuclear receptors and LEF1/CTNNB1 involves differential utilization of
CC two different activation regions. In association with CCAR1 enhances
CC GATA1- and MED1-mediated transcriptional activation from the gamma-
CC globin promoter during erythroid differentiation of K562
CC erythroleukemia cells (By similarity). {ECO:0000250|UniProtKB:Q8CGU1}.
CC -!- FUNCTION: Seems to enhance inorganic pyrophosphatase thus activating
CC phosphogluomutase (PMG). Probably functions as a component of the
CC calphoglin complex, which is involved in linking cellular metabolism
CC (phosphate and glucose metabolism) with other core functions including
CC protein synthesis and degradation, calcium signaling and cell growth
CC (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Part of a calphoglin complex consisting of CALCOCO1, PPA1 and
CC PGM (By similarity). Interacts with the bHLH-PAS domains of GRIP1, AHR
CC and ARNT. Interacts with CTNNB1 via both its N- and C-terminal regions.
CC Interacts with EP300. Interacts with CCAR1 (via N-terminus) and GATA1
CC (By similarity). {ECO:0000250|UniProtKB:Q8CGU1,
CC ECO:0000250|UniProtKB:Q9P1Z2}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC Note=Shuttles between nucleus and cytoplasm. {ECO:0000250}.
CC -!- DOMAIN: The C-terminal activation region (AD) is used for downstream
CC signaling. Seems to be essential for coactivator function with nuclear
CC receptors and with the aryl hydrocarbon receptor (By similarity).
CC {ECO:0000250}.
CC -!- DOMAIN: The N-terminal activation region (AD) is necessary and
CC sufficient for synergistic activation of LEF1-mediated transcription by
CC CTNNB1. Contains a EP3000 binding region which is important for
CC synergistic cooperation (By similarity). {ECO:0000250}.
CC -!- DOMAIN: Recruitment by nuclear receptors is accomplished by the
CC interaction of the coiled-coiled domain with p160 coactivators.
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the CALCOCO family. {ECO:0000305}.
