Input: Consider Input: Furthermore , the SH2 domain of p56 ( lck ) appeared to be required for pervanadate - induced NF - kappa B activation but not for Tyr42 phosphorylation .

Output: SH2 domain

Input: Consider Input: Transient expression analyses in cells of neuroglial and lymphocytic origin demonstrated that some of these LTRs had activities which varied significantly from the LAI LTR in U - 373 MG cells ( an astrocytoma cell line ) as well as in Jurkat cells ( a CD4 - positive lymphocyte cell line ) .

Output: LAI LTR

Input: Consider Input: The p12 ( I ) protein , encoded by the pX open reading frame I of the human T - lymphotropic virus type 1 ( HTLV - 1 ) , is a hydrophobic protein that localizes to the endoplasmic reticulum and the Golgi .
Output: hydrophobic protein
