CC -!- FUNCTION: Facilitates ubiquitin-independent proteasomal degradation of
CC polycomb protein CBX4. Plays a role in inhibiting the activity of
CC glucokinase GCK and both glucose-induced and basal insulin secretion.
CC {ECO:0000250|UniProtKB:D4AE48, ECO:0000250|UniProtKB:Q3TPJ7}.
CC -!- SUBUNIT: Interacts with GCK; the interaction occurs preferentially at
CC low glucose levels. {ECO:0000269|PubMed:24187134}.

CC -!- SUBCELLULAR LOCATION: Nucleus, nucleolus
CC {ECO:0000250|UniProtKB:Q3TPJ7}. Nucleus {ECO:0000269|PubMed:24187134}.
CC Cytoplasm, cytosol {ECO:0000269|PubMed:24187134}. Note=Detected in the
CC nucleus and nucleolus with no expression in the cytoplasm (By
CC similarity). However, a later study finds expression in the nucleus and
CC cytoplasm with no expression in the nucleolus (PubMed:24187134).
