Background： This gene is almost exclusively expressed in the brain, mainly in the neuronal layers. It encodes a protein that shows sequence similarity to bacterial DnaJ protein and the yeast homologs. In bacteria, this protein is implicated in protein folding and protein complex dissociation. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jul 2011],

Function：alternative products:Experimental confirmation may be lacking for some isoforms,similarity:Contains 1 J domain.,similarity:Contains 2 UIM (ubiquitin-interacting motif) repeats.,tissue specificity:Brain (neuronal layers). Weakly, in skeletal muscle and spleen.,

Subcellular Location：[Isoform 2]: Cytoplasm . Nucleus .; [Isoform 1]: Endoplasmic reticulum membrane ; Lipid-anchor ; Cytoplasmic side .

Expression：More abundantly expressed in neocortex, cerebellum, spinal cord and retina where it is expressed by neuronal cells (at protein level) (PubMed:1599432, PubMed:12754272). Detected at much lower level in non-neuronal tissues including kidney, lung, heart, skeletal muscle, spleen and testis (at protein level) (PubMed:12754272, PubMed:1599432). Isoform 1 is more abundant in neocortex and cerebellum compared to isoform 2 (at protein level) (PubMed:12754272).
