CC   -!- FUNCTION: Prevents transcriptional repression and induction of cell
CC       death by ENO1. May play a role in vesicular transport from endoplasmic
CC       reticulum to Golgi. {ECO:0000269|PubMed:11134351}.
CC   -!- SUBUNIT: Can homodimerize (By similarity). Part of the multisubunit
CC       TRAPP (transport protein particle) complex (PubMed:11805826). Interacts
CC       with ENO1 and TRAPPC2L (PubMed:11134351, PubMed:19416478). Interacts
CC       with PITX1, SF1 and TRAPPC3 (By similarity).
CC       {ECO:0000250|UniProtKB:P0DI81, ECO:0000269|PubMed:11134351,
CC       ECO:0000269|PubMed:11805826, ECO:0000269|PubMed:19416478}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P0DI81}.
CC       Cytoplasm, perinuclear region {ECO:0000269|PubMed:11134351}.
CC       Endoplasmic reticulum-Golgi intermediate compartment
CC       {ECO:0000250|UniProtKB:P0DI81}. Cytoplasm
CC       {ECO:0000250|UniProtKB:P0DI81}. Note=Localized in perinuclear granular
CC       structures. {ECO:0000250|UniProtKB:P0DI81}.
CC   -!- TISSUE SPECIFICITY: Expressed in brain, heart, kidney, liver, lung,
CC       pancreas, placenta, skeletal muscle, fetal cartilage, fibroblasts,
CC       placenta and lymphocytes. {ECO:0000269|PubMed:10431248}.
CC   -!- MISCELLANEOUS: The gene encoding this protein appears to have arisen by
CC       retrotransposition of a cDNA from the X-linked locus TRAPPC2. The site
CC       of integration of this retrotransposed cDNA appears to lie within an
CC       intron of the ZNF547 gene, which provides a promoter and non-coding 5'
CC       exon. TRAPPC2 and this protein are indistinguishable at protein level,
CC       and both proteins have been identified and functionally characterized.
CC   -!- SIMILARITY: Belongs to the TRAPP small subunits family. Sedlin
CC       subfamily. {ECO:0000305}.
