PITH domain superfamily (IPR037047)

Short name: PITH_dom_sf

Overlapping entries


This entry represents the PITH domain superfamily (derived from Proteasome-Interacting THioredoxin). The protein Txnl1, which is a probable component of the 32 kDa 26S proteasome, uses its C-terminal PITH domain to associate specifically with the 26S proteasome [PMID: 19349277].

The PITH domain is dominated by a jelly roll beta-sandwich structure. The beta-sandwich is formed by face-to-face packing of two anti-parallel beta-sheets. Another two-stranded beta-sheet seals off one end of the beta-barrel [PMID: 15741346, PMID: 20455272].
