Spindlin family member 2 (SPIN2), also known as SPIN.KS or SPIN2B, is a human protein encoded by the SPIN2 gene. It belongs to the Spindlin family characterized by tandem Tudor-like domains and a conserved N-terminal domain. Originally identified as a germ cell-associated protein, SPIN2 is involved in chromatin remodeling, transcriptional regulation, and epigenetic control. Its Tudor domains enable interactions with methylated histones, particularly H3K4me3 and H3K9me3. linking it to chromatin state modulation during gametogenesis and early development.
Recombinant SPIN2 protein is artificially expressed in systems like *E. coli* or mammalian cells for functional studies. Unlike its paralogs SPIN1/SPIN, SPIN2 exhibits tissue-specific expression patterns, with high levels in testes and ovaries, suggesting roles in germline development. Emerging research implicates SPIN2 in cell cycle regulation, stem cell pluripotency maintenance, and tumorigenesis. Aberrant expression has been observed in certain cancers, though its exact oncogenic mechanisms remain under investigation. Structural studies reveal unique hydrophobic cavities in its Tudor domains that differentiate SPIN2 from other family members, potentially explaining substrate selectivity. Current applications of recombinant SPIN2 include elucidating reproductive biology, epigenetic inheritance, and exploring therapeutic strategies targeting chromatin-modifying proteins in disease contexts.
