| DNA/RNA |
| Description | The SLC39A1 gene contains 5 exons, three of which are coding. The length of the gene is 8600 base pairs according to the Entrez Gene database. Several transcripts have been reported containing either 3, 4, or 5 exons. However, the coding sequence for SLC39A1 is the same for all reported transcripts. |
| Transcription | Only a single isoform has been reported; mRNA 2445 bases in length; coding region of 975 bases. |
| Pseudogene | None reported. |
| Protein |
| Description | SLC39A1 encodes Zrt/Irt-like protein family member 1 (ZIP1). ZIP1 is a 35 kDa molecular weight protein consisting of 324 amino acids. The protein contains 8 transmembrane spanning domains and shows the characteristics of a zinc transporter (Gaither and Eide, 2001). |
| Expression | ZIP1 is ubiquitously expressed in mammalian cells (Gaither and Eide, 2001). Expression is down regulated in prostate malignancy (Franklin et al., 2005). Its constitutive expression is reported to be regulated by SP and CREB1 (Makhov et al., 2009). Down regulation of expression in prostate malignancy is reported due to transcription repression by ras response element binding protein-1 (RREB-1) (Milon et al., 2010). |
| Localisation | ZIP1 is located at the cell membrane. |
| Function | ZIP1 is a facilitated zinc uptake transporter (Franklin et al., 2003). Activity of the transporter results in the intracellular accumulation of zinc. ZIP1 is involved in apoptosis induction in prostate cancer cells. |
| Homology | Mus musculus Slc39a1; Rattus norvegicus Slc39a1; Bos taurus Slc39a1; Danio rerio slc39a1. |

| Note | SLC39A1 is down regulated in prostate cancer (Franklin et al., 2005). Knockdown of the SLC39A1 expression decreases cellular zinc and increases growth of PC-3 cells (Franklin et al., 2003). Over expression of SLC39A1 inhibits prostate tumor growth in a xenograft model (Golovine et al., 2008). |
