`LaTeX-expl3-syntax-table' is still there, but expl3.el is now loaded
mostly with `docTeX-mode'. This is what I see in a regular .tex file:
character: : (displayed as :) (codepoint 58, #o72, #x3a)
charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x3A
script: latin
syntax: . which means: punctuation
character: _ (displayed as _) (codepoint 95, #o137, #x5f)
charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x5F
script: latin
syntax: . which means: punctuation

That shouldn't be necessary. I presume you're using AUCTeX 14.2.0?
Best, Arash
