Ribosomal L1 Domain Containing Protein 1 (RSL1D1)

PBK1; L12; CSIG; CATX11; Cellular senescence-inhibited gene protein

Ribosomal L1 Domain Containing Protein 1 (RSL1D1)
RSL1D1 belongs to the ribosomal protein L1P family. Highly divergent. PBK1 was cloned from a first trimester placenta cDNA library and was characterized. The 1908-bp gene fragment contains an open reading frame of 1551 bp and an Alu-sequence in the 3' non-coding region. According to Northern blot analysis on JAr choriocarcinoma cells, the fragment is close to full-length cDNA.
By in situ hybridization, PBK1 was detected only in first trimester but not term placentae in the proximal parts of cell islands and in closely adjacent villous cytotrophoblast. This expression pattern suggests that the newly identified molecule, PBK1, could be involved in the regulation of proliferation/ differentiation and potentially in invasion of trophoblast cells.
