YBX1
This gene encodes a highly conserved cold shock domain protein that has broad nucleic acid binding properties. The encoded protein functions as both a DNA and RNA binding protein and has been implicated in numerous cellular processes including regulation of transcription and translation, pre-mRNA splicing, DNA reparation and mRNA packaging. This protein is also a component of messenger ribonucleoprotein (mRNP) complexes and may have a role in microRNA processing. This protein can be secreted through non-classical pathways and functions as an extracellular mitogen. Aberrant expression of the gene is associated with cancer proliferation in numerous tissues. This gene may be a prognostic marker for poor outcome and drug resistance in certain cancers. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on multiple chromosomes. [provided by RefSeq, Sep 2015]

Interaction
Homodimer in the presence of ATP (PubMed:10817758, PubMed:11851341). Component of the coding region determinant (CRD)-mediated complex, composed of DHX9, HNRNPU, IGF2BP1, SYNCRIP and YBX1 (PubMed:19029303). Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs (PubMed:17289661). Component of the U11/U12 snRNPs that are part of the U12-type spliceosome (PubMed:15146077). Identified in a histone pre-mRNA complex, at least composed of ERI1, LSM11, SLBP, SNRPB, SYNCRIP and YBX1 (By similarity). Interacts with IGF2BP1 and RBBP6 (PubMed:17289661, PubMed:18851979). Component of cytoplasmic messenger ribonucleoprotein particles (mRNPs) (PubMed:19029303). Interacts with AKT1, MBNL1, SFRS9, SFRS12, ALYREF/THOC4, MSH2, XRCC5, WRN and NCL (PubMed:12604611, PubMed:14559993, PubMed:14718551, PubMed:15806160, PubMed:18335541). Interacts (via C-terminus) with APEX1 (via N-terminus); the interaction is increased with APEX1 acetylated at 'Lys-6' and 'Lys-7' (PubMed:18809583). Interacts with AGO1 and AGO2 (PubMed:17932509). Interacts with ANKRD2 (PubMed:15136035). Interacts with DERA (PubMed:25229427). Interacts with FMR1; this interaction occurs in association with polyribosome (By similarity). Interacts with ZBTB7B (By similarity). Interacts with HDGF (isoform 1) (PubMed:26845719). Interacts with ELAVL1; leading to ELAVL1 recruitment on C5-methylcytosine (m5C)-containing mRNAs and subsequent mRNA stability (PubMed:31358969).
