CC -!- FUNCTION: Stimulates membrane curvature formation and subsequent
CC endoplasmic reticulum exit site (ERES) establishment by recruiting PI3K
CC complex I, leading to COPII vesicle-mediated transport
CC (PubMed:32690950). Promotes endoplasmic reticulum (ER) exit of cGAMP-
CC activated STING1 oligomers (PubMed:32690950).
CC {ECO:0000269|PubMed:32690950}.
CC -!- SUBUNIT: Interacts with STING1, PIK3C3, and ATG14; the STING1/STEEP1
CC interaction is increased upon STING1 cGAMP-activation and leads to
CC recruitment of PI3K complex I. {ECO:0000269|PubMed:32690950}.

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:29374277,
CC ECO:0000269|PubMed:32690950}. Cytoplasm {ECO:0000269|PubMed:32690950}.
CC Note=Detected in the nucleus and cell soma of various neuronal types.
CC {ECO:0000250|UniProtKB:Q8VDP2}.

CC Event=Alternative splicing; Named isoforms=3;

CC -!- DISEASE: Intellectual developmental disorder, X-linked 107 (XLID107)
CC [MIM:301013]: A form of intellectual disability, a disorder
CC characterized by significantly below average general intellectual
CC functioning associated with impairments in adaptive behavior and
CC manifested during the developmental period. Intellectual deficiency is
CC the only primary symptom of non-syndromic X-linked forms, while
CC syndromic forms present with associated physical, neurological and/or
CC psychiatric manifestations. {ECO:0000269|PubMed:29374277}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- SIMILARITY: Belongs to the STEEP1 family. {ECO:0000305}.
CC -!- CAUTION: May be duplicated on chromosome 8, within an intron of the
CC ERLIN2 gene. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAB96348.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
