Summary: Lymphocyte signaling adaptor protein
Lymphocyte signaling adaptor protein Provide feedback
This domain family is found in eukaryotes, and is typically between 144 and 156 amino acids in length. The family is found in association with PF07647 PF07653. There is a conserved LGKK sequence motif. SLY contains a Src homology 3 domain and a sterile alpha motif, suggesting that it functions as a signaling adaptor protein in lymphocytes.

InterPro entry IPR021090
This entry represents eukaryotic proteins that are typically between 144 and 156 amino acids in length. The entry is found in association with , . There is a conserved LGKK sequence motif. SAM/SH3 domain-containing proteins contain a Src homology 3 domain and a sterile alpha motif, suggesting that they may function as a signaling adaptor protein in lymphocytes [PUBMED:11470164].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the UniProtKB sequence database using the family HMM
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the SLY domain has been found. There are 2 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
